HannahB Posted April 17, 2022 Share Posted April 17, 2022 hi, i went walking in the north east of england and found this, it looked to be a fish jaw? i’m new to fossil collecting and finding as a hobby and i could be completely wrong but if anyone knows anything could you let me know? thanks it was found in a beck/stream, not directly on a coastline. could this be a fish jaw? or small animal jaw?

Fossildude19 Posted April 17, 2022 Share Posted April 17, 2022 Welcome to the Forum. I took the liberty of cropping and contrasting your photos. To me, this looks like a cross section through a water worn crinoid stem or through an orthocone cephalopod shell.

TqB Posted April 17, 2022 Share Posted April 17, 2022 (edited) Tim's right with crinoid. It'll be Carboniferous from there and has a typical form with a wide lumen (hollow down the middle). This is a pebble of Carboniferous crinoidal limestone. Edited April 17, 2022 by TqB 2 1 Tarquin Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 17, 2022 Share Posted April 17, 2022 (edited) For me, this image shows the fossil curving back around on the side of the stone, so i don't think it's crinoid or cephalopod. I think the remains of a brachiopod or bivalve valve. with associated shell fragments. Edited April 17, 2022 by Tidgy's Dad 1 1 1 Life's Good! Tortoise Friend.

Advantage Posted April 17, 2022 Share Posted April 17, 2022 Agree with Tim, section through a partial and eroded crinoid stem. Steve 1 Link to comment Share on other sites More sharing options...
ClearLake Posted April 17, 2022 Share Posted April 17, 2022 My first impression was of a very eroded brachiopod, but I’m not at all familiar with the fauna from the location, so.... 1 Link to comment Share on other sites More sharing options...
