t-tree Posted March 20, 2020 Share Posted March 20, 2020 As some of you will know i have been showing some of my uncommon find from my years of collecting from opencasts in Derbyshire,UK. This find is from the coal measures and is in coal shale that produced fish teeth , fish scales and bivalves it is 18mm long 5mm wide. I have posted it before along time ago can you give me your opinions of what you think it is Thank-you. 18mm x 5mm Cheers John 13 Be happy while you're living for you're a long time dead.

Fossildude19 Posted March 20, 2020 Share Posted March 20, 2020 Neat fossil John! It could be from any number of actinopterygian fishes from the Coal measures. @Archie 4 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Ruger9a Posted March 20, 2020 Share Posted March 20, 2020 Very nice specimen! Looks like it could be prepped a little to show some additional jaw section (right on photo). Could just be my eyes though. Link to comment Share on other sites More sharing options...
Ash Posted March 20, 2020 Share Posted March 20, 2020 Whack it in FOTM there’s no vertebrate entries yet.

Archie Posted March 20, 2020 Share Posted March 20, 2020 Brilliant find! Those striations at the base of the teeth are similar to those on Rhizodonts like Strepsodus but I think Tim is right with some sort of actinopterygian, the teeth of Rhizodonts tend be be more long and slender. 2 Link to comment Share on other sites More sharing options...
t-tree Posted March 21, 2020 Author Share Posted March 21, 2020 Thank- you all for for your comments and help actinopterygian jaw will replace (fish jaw) on my label now.

jdp Posted March 21, 2020 Share Posted March 21, 2020 The absence of clear acrodin caps on the teeth is throwing me for a loop, but that could be damage. General tooth shape might be consistent with something like Progyrolepis. There's clearly much more of this under the matrix. A little delicate prep might help me nail down a better ID for you. 5 Link to comment Share on other sites More sharing options...

That's right it is a fossil i have showed before but id was only fish jaw 1 hour ago, jdp said: The absence of clear acrodin caps on the teeth is throwing me for a loop, but that could be damage.

Unfortunately the matrix only covers the top right of the jaw the bottom right just fades at the surface and the matrix slightly dips away Thank-you for taking an interest in the jaw.
