I found A Fossil On The Beach And Puzzled

I discovered a Fossil on the Seaside and Wondered
Updated on March 22, 2017 Kathi moreContact Writer Discovering Widespread Fossils on Great Lakes Beaches
A favourite past time for a lot of is combing the beaches for interesting objects the surf washes in. Whether you are walking alongside the shoreline of the ocean or the nice Lakes in the USA, your imagination is on excessive alert to select something up you just cannot cross by! Instantly, something catches your eye! However, it isn’t driftwood or beach glass or even a reasonably rock. You may not know exactly why, however you suspect you discovered something that was as soon as a living creature.
Has this ever happened to you A deep sense of curiosity and childlike imagination drives us to seek out out what we may have picked up alongside our saltwater or freshwater shorelines. Having collected quite a couple of samples from Lake Michigan’s shoreline, myself, I finally determined at some point to satisfy my nagging curiosity and followed by means of with a rewarding investigation. The extra I learned about my stony sand-smoothed findings, the more I wished to know. I puzzled what the creatures could have appeared like when alive and how they survived. I also needed to know the way they showed up so prevalent along the contemporary water beaches. A while later, after many answered questions, I can honestly say I take pleasure in a cool hobby. Taking things a step additional, I have drawn illustrations of their residing beings and started a fossil site. You’ll find the link at the tip.
A few of probably the most prevalent fossils found alongside the good Lake’s beaches are crinoids (shown in the images to the correct). They’ve been coined with a a number of names as a result of animal’s options and by the character of their fossils found throughout historical past. One frequent identify for them is “Indian Beads”. Native Americans had been recognized to make necklaces with their broken up items which resemble the shape of beads excellent for stringing. They’ve also been referred to as “Lucky Stones”! Spotting one takes a eager eye as many of the pieces are quite small.
As residing creatures, each circular section was stacked one over the other constructing the animal’s whole framework. They possessed branching arms that sat atop long single stems. They had been sessile creatures, in other words, they remained connected to the sea ground. Some varieties are recognized to have towered several meters in length. Their loose structure resulted in the residing organism’s beautifully coloured and flower like look which granted them the nickname of “Sea Lilies”. They captured tiny meals particles passing by on ocean currents with their feathery network of arms that functioned like traps. Crinoids match into the phylum of Echinoderm, meaning spiny pores and skin, and are cousins of starfish, sea urchins and feather stars.
Sea lily crinoid’s lengthy historical past started throughout the Ordovician Period round 500 million years in the past, although most fossils are from the Mississipian Period round 345 mya and are preserved in limestone. Right this moment there are far fewer species and most lack the long meandering stem widespread in Paleozoic varieties.
Within the course my investigation, I had often questioned why so many crinoid fossils ended up along the great Lakes; notably by the truth that they had thrived in saltwater environments. I’ve since discovered they can be found widespread in North America. A part of the reply to my inquiry is straightforward sufficient to clarify. During their lifetime, much of the world’s continents had been coated below heat shallow oceans, together with parts of North America. So how is it their fossils are so common near the large lakes The answer is as a result of ten thousand years in the past when the giant glaciers sculpted the deep basins forming the great Lakes, they also dug into the deep layers the place their stays rested. In the method, they had been deposited where we now can discover them and revel in their secrets, in addition to that of different species from the identical era.
Another widespread seaside find, bryozoans are sometimes referred to as lace corals because of their delicately threaded look, however they are not true corals. As an alternative, they’re moss-like animals belonging to the family of Fenestellida for their fan-formed, mesh appearance. They reside in tight colonies sculpted by arduous, limy, branching constructions. The colony consists of thousands of particular person animals referred to as “zooids”. Every particular person zooid lives inside its own limy tube referred to as a zooecium. The zooecium are the size of sewing needles. A single zooid begins the colony. A bryozoan colony has been noticed rising from a single zooid to 38,000 in simply five months. Each extra zooid is a clone of the very first one.
Interesting how they feed, Every zooid has an opening by way of which long sleeve polo stone island the animal can extend its ring of tentacles called lophophores. Their lophophores seize microscopic plankton from the water passing by. If one zooid receives meals, it nourishes the neighboring zooids as a result of they are joined by strands of protoplasm. If solely we people might be extra like them guaranteeing everybody on the planet is fed!
Their fossil record dates back 500 mya with 15,000 recognized species. Right this moment there are about 3,500 living species.
I discovered these clam fossils on the shore of Oval Beach in Southwestern Michigan. The shell of the darker pattern has been utterly replaced by minerals and is petrified to stone. Its clean floor is a telltale demonstration of the lake’s sand and water motion. The lighter coloured pattern clearly reveals the hardened muddy sediment that has completely encrusted its shell.
“Clam” generally is a term that covers all bivalves. Some clams bury themselves in sand and breathe by extending a tube to the water’s surface. Bivalve oysters and mussels attach themselves to exhausting objects and scallops can free swim by flapping their valves together. Every kind lack a head and usually don’t have any eyes, though scallops are a notable exception. With the use of two adductor muscles they’ll open and close their shells tightly. Very fittingly, the phrase “clam” gives rise to the metaphor “to clam up”, which means to stop talking or listening.
Bivalves have occupied Earth as early as the Cambrian Period 510 million years in the past, however they had been particularly ample in the course of the Devonian Period around four hundred million years in the past. Their fossils are found in all marine ecosystems and most commonly in near shore environments. In 2007, off the coast of Iceland, a clam was discovered to be a minimum of 405 years previous. It was declared the world’s oldest dwelling creature by North Wales, Bangor College researchers.
No different organisms typify the Age of Invertebrates more than brachiopods. They are probably the most plentiful Paleozic fossils, except for maybe trilobites. Paleontologists use them to this point rocks and different fossils. Numerous billions accumulated on the ocean ground with over 30,000 types. Immediately there are far fewer species, solely about 300 which stay mostly in cold water, deep ocean environments.
Brachiopods seem like clams however are very different inside. To inform them apart, clams have uneven formed shells, but each high and backside halves are identical. Brachiopods are symmetrical at a look, but the underside shell is smaller. Brachiopods are commonly known as “lampshells” because of their similarity in shape to a Roman oil lamp.
They live in communities connected to objects by a muscular foot referred to as a pedicle. They pressure water in and out of their shells filtering microorganisms with their lophophores, a crown of tentacles.
Through the Devonian time slot, over 350 million years in the past, Michigan was lined by a shallow saltwater sea. That’s where mass colonies of corals called Hexagonaria, percarinata, generally known as Petoskey Stones, thrived and flourished. The saltwater seascape must have been lit up with a quilt-work of colours by the mass colonies. Unfortunately, they turned extinct at the top of the Permian Interval’s mass extinction.
The identify “Petoskey” originated from an Ottawa fur-trader chief named Petosegay. A northern Michigan city was named after him, only the title was modified to Petoskey. Due to their abundance along long sleeve polo stone island Michigan shorelines, particularly within the northern areas close to Petoskey, Governor George Romney signed a invoice in 1965 that made the Petoskey Stone the official state stone.
When observing one of many fossils, every coral hexagon construction, seen to the eye, held a single animal which opened a mouth to expose tentacles. The tentacles took in meals and were additionally used to sting any organism or different corallite that got here too close. Calcite, silica and other minerals changed the original corallite exoskeleton.
An extinct order of coral known as tabulate corals additionally formed reefs and lived in warm shallow waters during the identical interval because the Petoskey Stone corals. They have been the favosite corals. The tabulae (horizontal inner layers) were built outward as the organism grew. These layers can clearly be seen within the photo to the best. The favosites can also be recognized by the honeycomb sample on the exterior of their fossilized remains.
Hope you have enjoyed my fossil discoveries. Next time you visit the seashore, keep your eyes open for a fossil discovery of your personal. You are welcome to use my hub or visit my fossil blog to help make an identification!

Nice introduction to fossils and fossil attempting to find novices Kathi.
I like the line:
‘A deep sense of curiosity and childlike imagination drives some of us to search out out what we picked up alongside the freshwater shoreline.’
That’s the unlucky point I feel. For some cause, as folks develop out of childhood too many lose their childhood fascination for such issues as fossils, as well as other wonders just like the creatures which live in a pond, or the stars to be seen within the night time sky. That’s unhappy – if only everyone might keep that sense of curiosity and imagination as they grow up – the world can be a way more wondrous place for all – adults, as well as children.
I hope some no less than feel impressed as they walk alongside a shoreline or beside a cliff face, to show over a couple of stones and see what they’ll find. Alun

Yes, Fossillady, I did enjoy this. This has been an afternoon of studying. I’ve learn so many interesting articles this afternoon and this one is certainly one I will remember. I had no concept. It’s wonderful how a lot there’s to study fossils.
Sending many Angels your way this afternoon. 🙂 ps

Hey this is so cool i simply bought my first fossil and wana discuss with individuals abot these things . somebody text me haha
Hey Micky, good to see you, sorry so late as I have been so busy these days with new jobs and all! I miss the common contact with all my hubber associates! Thank you for the nice remark, you are very variety to say so! Hope the whole lot is great with you! Hugs my pal

Your hubs are so pretty! Thanks pricey Fossillady!
Ha, What do you know, I’m a geo-jokster and do not even understand it…hee
Ha fossillady something new…LOL and were talking about fossil Ha that’s a great geo-joke…
Extraordinarily happy with this discussion Tom and Birdy, learned something new!!!!!
I assume it is sort of a tree with the circles. Attention-grabbing.
I am fairly sure the accretion strains on the top of a clam will reveal its age-just like the rings on a tree the clam gets bigger and one other ring is added-

I’ll speak fossils with you any day. I am in touch with both sides of my brain! Sometimes I surprise myself, lol.
“In 2007, off the coast of Iceland, a clam was found to be at least 405 years previous. It was declared the world’s oldest living creature by North Wales, Bangor College researchers.” How do they know this and where is the clam at now How does one decide the age of a clam that has seen centuries pass Oh, I think a poem simply got here to thoughts. Each sides of that brain are reacting at the same time.
Thanks for an excellent and nicely researched Hub.
Very kind of you Janet! I had never worked with pastels before so there’s a number of room for enchancment, they’re principally targeted for children! Subsequent time you are at the beach or in nature I hope you can acknowledge a few of these fossils!

Very attention-grabbing hub,Fossillady !Very informative and I like the artwork! It is superior.I by no means knew some of these were fossils! Well,I sure discovered Stone Island Jackets one thing tonight!
Thanks for sharing each information and artwork…nice combo!
i know its kinda funny I all the time favored Ross too and my wife would all the time look at me when he would say something geological…
don’t be concerned- put up a fossily hub i am going to read it…
ya got one fan…its a start
I know what you mean, no one needs to speak about fossils with me both. Reminds me of Ross on Friends. He always wants to share his details about fossils and the others won’t have something to do with it!lol
I am simply glad to talk fossils ith someone- my kids likem however.. even they tire of trying fast
Great recommendation Tom, Very a lot appreciated!
When cleaning crinoids- ya gotta know what kinda rock is clinging to them- will depend on the rock type you findem in round here it iseasily found in shale i normally rtry to clip off- the most effective i can with toe nail clippers – be careful- then i’ll use a pretty dilute HCL solution between .1 and .25 dilute-use a “gentle wire brush” maybe nylon brush-ajust hcl to rockhardness- at all times use acid in wellventilated area use safety glasses and neoprene or nitrile gloves- sandstone embeds- may be picked off the crinoids and a final acid wash
Hello Workingmom, Good to see you here! I wish I had advise for cleansing fossils, I might suppose as long as you do not use something too harsh,it will likely be okay!
It appears like it is not all that hard for you to find the crinoids the place you are! I get so excited whenever I can spot one! lol…take care!

Love this hub! I was actually desirous about writing a hub about crinoid beads (actually about using them to create jewelry, since I do this). My husband is an novice archaeologist (aka rock hound), and he started taking me with him once we first began dating. I didn’t care much about discovering the arrowheads that he was searching, but I fell in love with the beads! We had been just down in Monroe Co.KY, and found quite a few inside a couple of minutes by a few of the various creeks. By the way in which, do you know a good technique for cleansing fossils I need to clean these beads if I’m going to make jewelry out of them!
Hi Tom,Oh it appears like a rick fossil discover space. I have never found a trilobite, my husband did as soon as while working on the railroad. I like to find crinoids which might be nonetheless attach, nevertheless it would be even better to find one absolutely intact! Thanks for stopping by!

We have now the sme devonian aged fossils close to Lake Erie- that shallow sea was actually big when my son went searching with me he said what are all these nuts and washers doing right here-on the bottom in fact we were in a crinoid rich space. There have been a ton of Brac’s s well-then we found some smaller trilobite halves and a had a fantastic time diggin the dirt and shale shards He stored pulling up shale and asking what it was then he gave me one with a Trilobite trace fossil (imprint) it was really a great one
Hello WillStarr, You made your youngsters feel very particular that day! An exquisite fatherly factor to say. I would like to go to Kentucky and take a look at the shale financial institution. Kentucky has several fossil sites I’ve examine! I recognize you from other hubs and that i see you’re now following me, proper back at ya!
WillStarr 6 years ago from Phoenix, Arizona
The Kentucky farm the place we lived for just a few years had a shale bank on one facet of a stream that was loaded with fossils. My kids had been fascinated once i told them they were looking on the beginnings of life on Earth, and that their eyes had been the primary human eyes to ever see what they’d discovered.
Great, I am glad you made a new discovery, I hope you find numerous fossils! It really is enjoyable when you find one! It is gratifying later when you possibly can establish it!

Wowwee! Great hub. I reside in Long Island New York, where there are miles and miles of beaches. I never knew a number of the things I was looking at might be fossils. When the weather is hotter I will revisit your hub to look and study extra. Thanks for educating me. Rated up and superior.
My jaw dropped whenever you mentioned coelacanth fish that was found! I’ve learn that too! I would love to return there and fossil hunt. I’ve never been throughout the ocean. Hope to try this before my day comes round!
Nell Rose 6 years ago from England
Hi, it’s best to come over to England, you would have a fantastic time! lol the last time I went to Lyme Regis, Jurassic coast, they had been filming for Tv, and they’d a fossil programme full of all they had found, I might think about that there are nonetheless loads of what we believe to be extinct animals still on the market living in the deep ocean, I remember studying that fishermen discovered a coelacanth fish nonetheless living again in 1933, and i consider they have caught a few extra since then, so that you by no means know! cheers nell
Well, you will have made my day and that i hope yours is full of love and joy! Hugs

As a matter of truth I am working on one partly thanks to your encouragement! It is way appreciated!
..Hey Kathi – sure I love to stroll along my beach within the spring, summer season and fall and decide up ‘found objects’ and flotsam and jetsam washed in from the tide particularly after a storm or high winds however as I speak there’s a lot snow and ice down there right now you can’t see something besides a big blanket of white – everywhere you look – I imagine I will have to attend until the spring now to find something new and get back to my days of ‘beachcombing’ …….when you have any extra images about your days at the seaside or just round where you reside it could be good to see you make another photographic hub on that subject ……

I am unable to assist however feel sorry for poor deaf kitty, but I’m positive he/she’s in good palms. We have the identical lake impact on the west coast of Michigan brought on by the westerly winds. In actual fact we’re in a snow belt area. Last couple of years we’ve had file snowfall over one hundred twenty inches. Do you choose up fossils whenever you stroll the beach Thanks again on your support!

…absolutely fascinating hub topic you could have written about here …. I live on the northern shores of Lake Erie in Ontario, Canada and i walk everyday alongside my seaside with my deaf cat (on a leash). I dwell 100 toes away from the lake ……and that i always see flotsam and jetsam and found objects that are washed up every day whether or not it be man made or miracles of natures.
By the way how is the weather where you reside
We frequently get what is called lake effect circumstances because of the winds off the lake.
Again you might have actually achieved some wonderful research here in your hub and can be a worthy addition in any classroom!

Very cool hub , I’ve a friend I am going to indicate this to. They are in all probability on the seaside right this minute on the west coast amassing shells as I write this!
