Diplotomodon Posted September 7, 2019 Share Posted September 7, 2019 On a whim I decided to stop by the Big Brook site in NJ to see what might have washed up after the rain yesterday...not a lot of shark teeth at all but plenty of weird mammal bits for some reason! I'm not good at all with figuring out mammal material so I figured I'd post some pictures to the forum and get people's thoughts. (Also I suppose it remains to be seen whether this is genuine Pleistocene material or stained, semi-recent bones...) These are smartphone pics (& Android at that) so excuse the quality. This first one is a tiny jaw of what I'm assuming is a rodent of some kind - the size is really throwing me off here. The same jaw is here on the bottom alongside a couple goblin sharks, plus an end of a random limb bone up top. Horse teeth? (The ends on both are broken, unfortunately - these are the most distinctive edges) (image size limit reached, more in next post) What a wonderful menagerie! Who would believe that such as register lay buried in the strata? To open the leaves, to unroll the papyrus, has been an intensely interesting though difficult work, having all the excitement and marvelous development of a romance. And yet the volume is only partly read. Many a new page I fancy will yet be opened. -- Edward Hitchcock, 1858 Formerly known on the forum as Crimsonraptor @Diplotomodon on Twitter Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 7, 2019 Share Posted September 7, 2019 We need a shot of the opposite side of the jaw, and one looking down on the tooth surfaces. There is a 4 mb limit per post.

Diplotomodon Posted September 7, 2019 Author Share Posted September 7, 2019 I also screened up this bird bone, of all things - completely surprised that it survived tumbling around on the streambed. Is it Pleistocene, or fairly modern? This is the find I'm most curious about...it looks vaguely tooth-like. Could be palatal material of some kind? If anyone needs better pictures let me know and I can see if I can dig up a hand lens. It was a productive day at the brooks today! (even I did only scratch up three shark teeth lol) What a wonderful menagerie! Who would believe that such as register lay buried in the strata?

Diplotomodon Posted September 7, 2019 Author Share Posted September 7, 2019 More pictures of the jaw...it's about 12mm long and 6mm tall What a wonderful menagerie!

caldigger Posted September 7, 2019 Share Posted September 7, 2019 If you get in the habit of cropping your pictures so it has minimal space around your items this will enlarge your pictures quite a bit. 21 minutes ago, MarcoSr said: The below specimen looks like a Chimaera jaw.

The Jersey Devil Posted September 8, 2019 Share Posted September 8, 2019 The first thing is a modern rodent jaw. In the group pic the two teeth are sand tigers. The thing up top looks more like a modern twig piece. The “horse teeth” are pieces of modern bone. I agree that the next thing is modern bird bone. The last specimen is a nice Ischyodus mandibular. 1 “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...
