From the album: Odd and Rare Shark Teeth
A 340-360 Million year old Stethacanthus tooth from Caney Shale, Oklahoma. -
This silvery gray crown of a fossil Crinoid is quite impressive for its vascular arrangement of arms and protruding aboral cup. However, it is the nature of its preservation that makes this piece very special. The fossil is pyritized as the metallic mineral Pyrite replaced the organic matter during mineralization.

This is roughly 2 1/2 inch in length. At its widest point 1 1/2 in and a 1/4 in thick. Any help identifying it would be much appreciated

Here is a limestone reef rock from Tucki Mountain in Death Valley. The strata is vertical. There was a band of reef rock several hundred feet across. Lots of crinoids but it's the sponge / archaeocyathan fossils that I'd like to know about. This is the first time I've done this, so I'm not sure how the answers arrive... Thanks very much! Dick

Here are some color pencil sketches of some Paleozoic agnathans I drew many years ago (maybe 6 or 7 years ago). Time is scarce, but seeing these again I somehow feel inclined to start sketching some new concepts again Polybranchiaspis yunannensis (Galeaspida) Early Devonian Qujing, Yunnan, China Haikouella lanceolata (Agnatha, Haikouellidae) Early Cambrian Chengjiang, Yunnan, China Stensiopelta pustulosa (Cephalaspida) Early Devonian Ternopil, Ukraine Pteraspis (Pteraspiformes) Early Devonian Ternopil, Ukraine

Hey guys, So I discovered there is actually GO transit service from Hamilton, Ontario to Brantford, Ontario and Im actually excited to discover this (HOORAY!!). Does anyone know the geology of the city? Im also looking for papers/files that can help me know what to find there. Thanks for any help!

I just went to this traveling exhibit in a museum in a city where my brother lives that it is about the animals and life in the Permian period and I got pictures of 3 fossils, an ammonite, a trilobite and a crinoid but I don’t know what species and genus they are?

I visited a small Paleozoic (Silurian) coral reef in Indiana the other day. No earth-shattering, jaw-dropping discoveries, but it's an interesting spot with dolomitized fossils. Here's a google earth view of the center of the reef. A nice mollusk, if anyone knows what species, let me know. It shattered when I tried to extract it, but I was able to glue it back together as you can see here. Sphaerexochus romingeri cephalon After extraction.. I believe this is a Platyceras: To be continued..

Hey guys do any of you know where I can find Some placoderms here in Black Hawk County Iowa? I have only found a plate piece here and some of my friends found some WHOLE PLACODERMS. while I only have one tiny plate. If you can help me please and thank you!

Hello, I'm 12 years old and my name is Kenan S. I think I have found a new species inside a Tabulate Coral! There seems to be tiny bivalves inside of the coral after I split the coral in half. Wherever the growths are there is a cavity in the coral missing from the region. Also something new to my notes on this coral is that it grows hexagons (like any Tabulate coral) but over each other, but when the 'parasite' eats at the coral it does not grow over the spot or just makes a couple new polyps like any other coral (I own a couple living corals in my 75 gal) it kills the surrounding couple polyps, and creates a new area of polyps. I put this find under this category because of how small the parasitic creatures are. I can barely see them with my own eyes and my microscope is currently broken so that's that.

Can anyone identify the possible location where these might have been picked up? These are some of the last remaining unidentified and un-located items that I acquired from the old rockhound couple in Nanaimo, that caused me to come to TFF for ID help in the first place. I'm only getting around to it now. These aren't the most spectacular or important fossils, but it's always worth it if you can attach some info to them. Otherwise I'll eventually toss them out for garden rockery, probably. I thought I saw some similar items that someone had posted not too long ago, from a river in Ontario, in a town that started with P - Pickering? But I never followed up on it and I can't find that topic now. I suspect these are all from the same area, whatever area that is. They're all Paleozoic marine, and all but #3 are water-worn. First: This first piece I have already posted but I never got any confident answers about it. Maybe combined with the others I'll get further with it.

Found associated with T. rougensis, T. spinosus, brachiopods, cephalopods, and graptolites. Included in multi plate alongside eight other complete or near complete T. eatoni.

From the album: Sharks and fish
The shark relative is genus of eugenodontia holocephalid from the Carboniferous-Pennsylvanian age Anna shale formation, Carbondale group, found in different Illinois coal mines. I dont know(yet)which mine these were found in. This unidentified species is of the "vorax-serratus- crenulatus-heinrichi" or "E. heinrichi group", with the teeth being more of a standard triangular shape, as opposed to being thinner and pointed at a forward angle as in the "E. minor" group http://www.thefossilforum.com/applications/core/interface/file/attachment.php?id=501751 -
