brad hinkelman Posted February 5, 2017 Share Posted February 5, 2017 I'm assuming first is a shark vert, amy help on species or size of shark? and also not sure what the second item is...thanks Link to comment Share on other sites More sharing options...
Doctor Mud Posted February 5, 2017 Share Posted February 5, 2017 Hi there, definitely a shark vert. What age are these sediments? It can be hard to pin down shark species from verts alone, but likely candidates for a given time period can be suggested. The second item looks like a shrimp burrow, reminds me of Ophiomorpha. 2 Link to comment Share on other sites More sharing options...
erose Posted February 5, 2017 Share Posted February 5, 2017 Yes indeed on the shark vert. Good specimen. The second object is quite interesting. At first it looks like the burrow-fill trace fossil Ophiomorpha, but it isn't. There are burrows filled with small fecal pellets that appear similar as well, but I am not sure about this being one of those either. The neat bit is that "worm" tube running down one side. Never seen anything quite like it. And then again, hopefully not throwing cold water on it, it could be another weird iron nodule/concretion... Thanks for sharing.

erose Posted February 5, 2017 Share Posted February 5, 2017 Too many species of shark in those sediments. You can distinguish lamniform sharks from the batoids by shape. The "angel shark" verts are also distinct. Bony fish will be longer than wide. Beyond that I had always been told, short of finding a set of teeth at the end of an articulated spinal column identification even to genus is at best a SWAG. 2 Link to comment Share on other sites More sharing options...

MarcoSr Posted February 5, 2017 Share Posted February 5, 2017 The vertebra looks more like a sawfish vertebra to me than a shark vertebra.

njfossilhunter Posted February 5, 2017 Share Posted February 5, 2017 I also believe the vert is a Saw fish...I posted a picture of mine below and what I think the second fossil is a belemnite that has been extensively borrowed by Cliona cretacica. That long thinke is also some kind of borrow I have found also but I'm not sure exactly what it is. Here is my Sawfish vert Here is the result of what Cliona cretacica does 4 TonyThe Brooks Are Like A Box Of Chocolates,,,, You Never Know What You'll Find.

Shrimp burrows are nodular. 1 Link to comment Share on other sites More sharing options...
History Hunter02 Posted February 6, 2017 Share Posted February 6, 2017 The second one kind of looks like iron. Have you tried putting a magnet over it? Nice shark vertebra. 1 Link to comment Share on other sites More sharing options...
Carl Posted February 6, 2017 Share Posted February 6, 2017 I agree with Tony. The second piece looks like a "ghost" of a belemnite guard created by the infilled burrows of Cliona. Pretty rare and special! 1 Link to comment Share on other sites More sharing options...
The Jersey Devil Posted February 15, 2017 Share Posted February 15, 2017 @njfossilhunter Hello njfossilhunter, I was just wondering how you distinguish between shark vertebrae and Sawfish vertebrae. These are from the Late Cretaceous sawfish Ischyrhiza mira, right? I appreciate the help. “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...

These are where soft cartilage processes once were. Sawfish centra lack these. Sawfish still had the processes, but they weren't attached inside the centrum. 2 Link to comment Share on other sites More sharing options...
