jwcounts Posted August 27, 2012 Share Posted August 27, 2012 I always keep the little fossil scraps from the North Sulfur River (Cretaceous) and examine them closer at home. This one had an interesting texture with lots of detail. It looks almost like scales. But looking at the back (the browner, fibrous looking picture) it looks more like plant material. I thought the pattern might be distinctive and someone might recognize it. Scale bar in the photo is in millimeters. Any ideas? I'm pretty sure it is not manmade. It has the characteristics and feel of all the other fossil bits out there. Link to comment Share on other sites More sharing options...
Mr. Edonihce Posted August 27, 2012 Share Posted August 27, 2012 reptile (or other) skin/dermal plating?

Auspex Posted August 27, 2012 Share Posted August 27, 2012 Boy howdy, that looks like what I think osteoderms should look like...no idea for what critter to suggest, though.

Auspex Posted August 27, 2012 Share Posted August 27, 2012 Really? Wow. All the elasmobranch cartilage I have seen has displayed a "rod-like" structure. This is an awesome piece!

Al Dente Posted August 31, 2012 Share Posted August 31, 2012 Here are a couple of examples of ray cartilage. The first one is a piece of the rostrum of the Eocene sawfish Pristis lathami: Here are a group of vertebrae including some cartilage from a recent clearnose skate Raja eglanteria: Link to comment Share on other sites More sharing options...
