RolleiPollei Posted April 13, 2017 Share Posted April 13, 2017 Hey guys, I'm new here and to fossil collecting in general and have made a couple trips to Big Brook. I've collected mostly shark teeth and the usual fossils in the area but the other day found this fragment of something. I wouldn't have thought too much about it but it has these odd ridges on a small part of the edge which baffles me and everyone whose seen it. Is this even a fossil and if so does anyone have any clue what it is from? Any information would be greatly appreciated. Link to comment Share on other sites More sharing options...

Vieira Posted April 13, 2017 Share Posted April 13, 2017 It looks like a fossil shell to me... Some kind of Oyster. Link to comment Share on other sites More sharing options...
Al Dente Posted April 13, 2017 Share Posted April 13, 2017 I agree with Vieira. You can see a muscle scar in the middle. Link to comment Share on other sites More sharing options...
Got Bones? Posted April 13, 2017 Share Posted April 13, 2017 This appears to be a fossil Exogyra costata with a minor section of the oyster missing.

Plax Posted April 13, 2017 Share Posted April 13, 2017 It's probably an Exogyra or Pycnodonte "lid". Very common downstream of Boundary Road Bridge. Scarce upstream of the bridge. Agreeing with Veira and Aldente and now Got Bones! Link to comment Share on other sites More sharing options...
RolleiPollei Posted April 13, 2017 Author Share Posted April 13, 2017 Thanks so much for the information! I figured it was an invertebrate of some kind but it looked a lot different and larger compared to all of the other oyster fossils you see everywhere in that site.

RolleiPollei Posted April 13, 2017 Author Share Posted April 13, 2017 On a side note these are the other fossils I found that day. The Squalicorax tooth on the bottom left is the most complete one I've found so far. Link to comment Share on other sites More sharing options...

Got Bones? Posted April 17, 2017 Share Posted April 17, 2017 Two of those are cow shark teeth, nice finds.

They are definitely not cow shark teeth.

Plax Posted May 18, 2017 Share Posted May 18, 2017 here's a case where scientific name is easier! Link to comment Share on other sites More sharing options...
