steviefossils Posted January 10, 2021 Share Posted January 10, 2021 (edited) I was fortunate enough to find many nice teeth during 2020. These are some of either my nicest, favorite, or somewhat uncommon finds from my searching at Big Brook, NJ. These finds are late cretaceous (~65 million years old). Sources for identification: http://www.njfossils.net/cover.html Fossil Shark Teeth of the world, by Cocke The first picture are 4 of my largest and most complete goblin teeth (Scapanorhynchus texanus), all found on the same day! I think it had rained overnight, though there was no rain in the forecast. I think this along with unseasonably high temperatures led to bit of erosion. Picture #2: Mackerel teeth Left to right, first is Cretolamna appendiculata (lata?) and the latter two: Archaeolamna kopingensis. Mackerel teeth are some of my favorite due to their shape and cusplet size. Picture #3: A branchial tooth from an early drum fish (Anomaeodus phasolus). More photos will be uploaded in a comment.

caterpillar Posted January 10, 2021 Share Posted January 10, 2021 Your fish tooth seems to be Eotrigonodon 1 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
Ludwigia Posted January 10, 2021 Share Posted January 10, 2021 Nice finds! Maybe @caterpillar should explain which fish tooth he means. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Jeffrey P Posted January 10, 2021 Share Posted January 10, 2021 Very good representative finds for the Cretaceous brooks of Central New Jersey. Congratulations. Looks like you did have a productive year. That drumfish tooth though I find especially interesting. I don't recall ever seeing one like that before.

I also did some additional googling, https://njfossils.com/hadrodus-priscus/ and https://www.fossilguy.com/sites/bbrook/bbrook_col.htm#fish list the tooth from Hadrodus, which is similar to Eotrigonodon (if those two sites are correct in their IDs). I believe your identification, especially since other members of the community agree, but I was curious as to how you made your conclusion. What features set it apart from the other fish? I'm going to purchase some literature on fossil fish identification to have some more reputable material than my usual websites. Thanks, Steve Link to comment Share on other sites More sharing options...

The first I found was in rough shape, and I didn't realize until I got home what it was. (I left it at the Brook) Link to comment Share on other sites More sharing options...

I made the ID of the drum from NJ fossils.net. But as you might see in the comments, another member is helping me out with the ID. Link to comment Share on other sites More sharing options...
