#fossil ID

[randomslasher]

My dad was in Canmore last week and visited the Burgess Shale. He found this fossil there (didn't take it obviously just took a picture of it) and I'm hoping someone on Tumblr might be able to help us ID it. He's thinking it might be a juvenile anomalocaris (I have doubts but I don't know enough to say for sure).

Hope this rock is some part of an coral fossil.

Like rugosa coral.

Hey Paleo or geology peeps! can anyone tell me what made this funky fossil I found in the river?? Could be dated to anywhere between Ordovician-Devonian iirc, never seen one like it before (found in southern Ontario)

[prasemvanguardgerman]

So to beginn the first speciemen of fossil for this post. Found today, not seen found before.

Likely some sort of porifea = sponge.

An with tiny silicat veins Astylospongia praemorsa.

After learning the name i got good reference pictures of it. My first find of this specimen!!

Findings of known deposits from astylospongia are in my area from belgium to middle germany poland to the baltic sea and goes up to north.

Brown like chert- flint near round bulb alike. Complete round underside without stem or breaks. Looking like an dry old fig fruit. 🤨

In wet condition its darker gray, with silica vein like struckture like some sponges have. Chestnut sized.

I leave the rugosa + horn coral species Id image here for the future, to lose quick compare.

Prepare some warning for annoying ads from the Researchgate site of the article on the link.

BTW, can anyone tell what is up with this rock?

It looks like a fossil, and my gut says "fossil skin," but I don't actually know. (The vendor I bought this from said he had no idea either, but was leaning towards "trilobite"?????)

@a-dinosaur-a-day these aren’t dinosaurs, but I thought you would like them. I got them at the gift shop at the Santa Barbara Museum of Natural History.

On the left is an opalized ammonite and on the right is something else. (I don’t remember what the label said.)

If you (or some other paleontologist) can tell me what the fossil on the right is, I’d be very grateful.

credit to artist and link to this piece’s etsy page. tumblr do you have any thoughts on the ID of this tooth? i just started looking into tooth classification tonight so i have no idea what im doing LOL i tried navigating it on my own, and came to Heptranchias howelli but i could also be entirely wrong, idk dentistry terms, lol

I don't think there's much else it could be. a quick google search reveals a lot of almost identical results:

also based on my own experience with my orthocerases (there's a tiny one on my big one):

so yeah, you're an orthoceras!

Greetings! I am Pencil! I am momentarily taking over Bee's (my new friends) blog to make this post!! (here's a selfie). Bee thinks I am of the genus Orthoceras, but is not entirely sure and would like a second opinion! I travel in Bee's pockets every day and sleep in a soup spoon with a lesbian flag sticker as a blanket. Could someone help figure out more about me? thanks 🦑

Don't Lick The Science (to see if it's a bone)

Although you can determine whether an object is a rock or a bone, here's an incomplete list of reasons not to do so:

It might be covered in animal urine/dung, if found outside

It's definitely covered in bat guano, if recovered from a cave

Just in general, it might be unsanitary and make you sick

You don't want someone else to handle something covered in your slobber

Human saliva could damage fragile specimens

Students in geology labs will baste hand samples with hydorchloric acid to see if the mineral reacts; these hand samples are not cleaned between lab sessions

There's a nonzero chance that the fossil will be radioactive

So again I need some suggestion help of the rock - fossil identification on this specimen.

It has the pattern like the chambers from modern „unions cells“ or, some piece of an petrified coral or sponge.

Dark grey non tranculent. Lightly weight.

Found on the yesterdays fossil hunt on the search with other rocks, flint shards from surrounding field works. Flat surface of rock, not polished to feel more like an rub over an tortoise shell. 🐢 But of course it’s isn’t.

In the zoom you can seen the struckture. Found on the same location of finds like the previous sponge and echinoids near field tracks. With lot of chert flint pebbles and chunks.

Has the form vaguely of an oyster shell but it isn’t one, has no cracks or rims like an shell struckture. More like an onion cell chambers, under an microscope.

Can’t tell which rock it is but likely with silicate parts.

The Google image search and reading of porifea or coral finds in forums doesn’t helped.

Posting it again. Have no idea suggesting part of an coral or likely sponge struckture petrified. Found on dry field land in the middle range of Germany, no direction to the sea or large rivers.

Looking for helping answers or hints of this mold in white flint , chert rock. Like an fossil ID.

Please zoom in. The find was in an northern region from middle germany.

Found by me on plain ground surrounded from rich farming ground. Sandy clay ground with an lot of chert flint quarz and other sedimentary rocks here.

Edit: the suggestion here lead to crinoid partial inprints, which here are not common to find.

My own rendition of the Berlin specimen, one of the most famous and beautiful fossils in the world. It contains an incredibly-complete skeleton of an Archaeopteryx, bones and feathers and all.
