Nick Fish Posted February 24, 2021 Share Posted February 24, 2021 Possible scute? Found in NJ cretaceous streams. Thoughts? Link to comment Share on other sites More sharing options...
val horn Posted February 24, 2021 Share Posted February 24, 2021 i think so, the cretaceous croc scutes that I have seen look like that. 1 Link to comment Share on other sites More sharing options...
Darktooth Posted February 24, 2021 Share Posted February 24, 2021 This might actually be a drum fish mouth plate. @frankh8147 @Trevor @The Jersey Devil 1 1 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

The Jersey Devil Posted February 25, 2021 Share Posted February 25, 2021 This is neither a drum fish mouth plate nor a Croc osteoderm. This is a reptilian bone fragment showing the internal porous structure. Drum fish aren't found in the Cretaceous. 2 “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...

Not in the taxonomic sense of Sciaenids but there are plenty of other cretaceous fish with crushing plate dentition that are often referred to as "Drumfish". It's erroneous, yes, but I doubt they're going to stop calling them drums. Link to comment Share on other sites More sharing options...

Forgive my uneducated opinion, but, aren't the holes a bit too circular for a bone structure? All of the reptilian fragments I've seen sport a more tubular structure. Going off my current information, I say croc osteoderm. ~ Isaac; www.isaactfm.com "Don't move!

ThePhysicist Posted February 25, 2021 Share Posted February 25, 2021 I agree that this is bone, and likely reptilian. This is a similar piece from the Cretaceous of TX, NSR. No crocs there. Turtle chunk from Galveston, TX: The bone is very spongey. 2 2 "Argumentation cannot suffice for the discovery of new work, since the subtlety of Nature is greater many times than the subtlety of argument." - Carl Sagan "I was born not knowing and have had only a little time to change that here and there." - Richard Feynman Collections: Hell Creek Microsite | Hell Creek/Lance | Dinosaurs | Sharks | Squamates | Post Oak Creek | North Sulphur River | Lee Creek | Aguja | Permian | Devonian | Triassic | Harding Sandstone Instagram: @thephysicist_tff Link to comment Share on other sites More sharing options...

Lone Hunter Posted February 26, 2021 Share Posted February 26, 2021 To my untrained eye that looks like a Cretaceous croc scute I have from North Texas, assuming mine is, would one of the differences be the distance between the holes? Link to comment Share on other sites More sharing options...
val horn Posted February 26, 2021 Share Posted February 26, 2021 I would find the shape of the surface characteristics very odd for a bone fragment, they are round and not sharp edged and have an even depth. Also they appear to me to be significantly larger than trabecular structure even in turtles or whales. As I said earlier it looks like cretaceous croc. More recent Croc scutes from florida pleistocene look different ,and have a rise in the middle. Link to comment Share on other sites More sharing options...
The Jersey Devil Posted February 26, 2021 Share Posted February 26, 2021 This is a typical bone fragment from NJ. A bunch of abrasion can easily completely reshape the bone frag. The more delicate structures in the bone get rounded off / destroyed and look like they have a pattern like a Croc osteoderm, but it is an illusion. 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...
MartynH Posted February 27, 2021 Share Posted February 27, 2021 (edited) I would say fragment of croc scute - the specimen is identical to the ones we find here on the Isle of Wight, slightly worn but quite identifiable.
