Prehistoric Ramanessin bone fragment?

Recommended Posts

Life Finds A Way

Hi all! Turning to Fossil Forum's wisdom as always for ID purposes. Found this bit in Ramanessin brook on a short dig. Split between if this is a skull bone fragment or simply a piece of ghost shrimp claw. Seems to fit more consistently with bone, just under the diameter size of a quarter. Any help back is appreciated.

More interestingly, and also for your ID is a few shots of what is believed to be an old croc tooth (and is quite pointy still), though the bottom root has a slight teardrop, and overall it has a slight curve along the side. Is about the diameter of a quarter, found in Big Brook separately. Will accept any opinions on it being another tooth, a concretion or something else entirely! Thanks!

These unfortunately look like the tricky ironstoneconcretions that litter the area. T

They really do take on some look-alike shapes. 

Unfortunately, even long time collectors can be foolded by these at times.

The first one is a piece of some steinkern.  The second is a concretion.

The first one looks like a gastropod steinkern; the second one is a concretion.

The images posted for the first specimen make me think that might have the pattern of  erosional / diagenetically transformed factors of the original crab claw (or relative), but I could be wrong. Try to compare the patterns of the images below.  Mine is not altered by the possible ferruginous content. (Miocene / Romania)

IDK about the first one, but I have been fooled by enough Ramenessin concretions to ID the second one as a concretion like the others said.
