Manticocerasman Posted March 5, 2019 Share Posted March 5, 2019 Last weekend we made a trip to my favorite Devonian hunting spot. As usual we found a few goniatites, but apart from this we found a lot of smaller fossils like brachiopods, crinoids and even a bivalve. and a few other nice surprises. The small bivalve: glyptohallicardia sp. 2 valves and pyritised, only a few mm wide with bot halves preserved. a very nice crinoid calyx a tiny brachiopod ( Lingula ) One of the best finds of the day was a fish tooth, I’m still unsure on the species, but I think something in the area of a Euchondrocephalid like Helodus. It the my oldest tooth in my collection Still, I did find an even better fossil , I’ll let you speculate on what this might be, but for now it is packed in the trunk of my car and I’m going to drop it off to the local institute Halfway on the way back home we spotted a construction site with a little bit of chalk coming out of the ground, we stopped for a prospection and came back with a few incomplete echinoids and 2 belemnites . So it is always worth to stop at an interesting looking spot 9 growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...

Al Dente Posted March 5, 2019 Share Posted March 5, 2019 Could this be a small placoderm jaw? I used to find similar ones in the Devonian of Iowa. 1 Link to comment Share on other sites More sharing options...

Hmm mabey, I was more inclined to think it was primitive shark tooth, it seems to have some enamel . but any insight is welcome :-) growing old is mandatory but growing up is optional.

DPS Ammonite Posted March 5, 2019 Share Posted March 5, 2019 It might be a conodont, part of a “worm” jaw. What is the scale? https://www.slideshare.net/mobile/kristinsheaffer/conodont-species My goal is to leave no stone or fossil unturned.

Tidgy's Dad Posted March 5, 2019 Share Posted March 5, 2019 Very nice finds! I really like the crinoid and tooth, but the bivalve and the inarticulate brachiopod are gorgeous. Always great to find a few bonus items when you make a speculative stop as well. Is the mystery item the scale of a fish? Life's Good! Tortoise Friend.

Thx Adam, it is not a fish scale, but you are on the right track, think bigger it is in the 3 big blocks right of the hammer, 2 of them are the positive and nagative. the 3d block on the right is coverd in mud, but contains more of the fossil. growing old is mandatory but growing up is optional.

Monica Posted March 6, 2019 Share Posted March 6, 2019 I'm with Adam - the pyritized bivalve and brachiopod are exquisite!!! Congratulations on your great finds, including the tooth and placoderm piece!!! 1 Link to comment Share on other sites More sharing options...
Paul1719 Posted March 6, 2019 Share Posted March 6, 2019 Are the parallel ridges of the placoderm plate surface ornamentation or internal structure? I assume this is near-shore marine? It must be pretty close to the Devonian tetrapod sites? Great finds! I am sitting here in Massachusetts looking out over a very white landscape with wind-chill about 3oF (-18oC)!

There are no tetrapod sites in our area. 1 hour ago, smt126 said: Awesome find on the placoderm, that matrix looks hard for prepping Thx Yes it is extremely hard matrix. I'm donating the pieces to our local institute, they have propper tools to remove it from the rocks. growing old is mandatory but growing up is optional.

Manticocerasman Posted March 7, 2019 Author Share Posted March 7, 2019 preppwork on a little goniatite that I found on this fieldtrip.
