wetwilly Posted February 5, 2016 Share Posted February 5, 2016 Hi, Found a few items that I am not sure what I have...again. I'm thinking this is shark cartilage. Ammonite? Ammonite? No clue: other side of same... Thanks in advance! Bill Link to comment Share on other sites More sharing options...
Guguita2104 Posted February 5, 2016 Share Posted February 5, 2016 Nice fossils ! For labell your third fossil as ammonite I think you should try to see if there are evidences of suture lines.However, for what I can I'll agree with worn ammonite fragment. About fourth I have some doubts,also...IMO, it could be a Gryphaeidae valve (maybe Pycnodonte sp.)Regards, Guguita Link to comment Share on other sites More sharing options...
abyssunder Posted February 5, 2016 Share Posted February 5, 2016 I'm wondering if the cephalopod couldn't be a flat Baculites body chamber. Is known that the Baculites usually breaks along the suture lines, which are vissible in your images.

Fossildude19 Posted February 5, 2016 Share Posted February 5, 2016 Your second item looks more arthropodish to me - maybe a bit of ghost shrimp?

wetwilly Posted February 5, 2016 Author Share Posted February 5, 2016 Thanks for the replies Guguita, Abyssunder and Tim. I realized after I posted item 2 (shark cartilage?) that it did not resemble the shark cartilage I found once before. Bill Bill Link to comment Share on other sites More sharing options...
Carl Posted February 8, 2016 Share Posted February 8, 2016 1. Probably a steinkern of a kind of snail with a very "stretched out" shell. I've found many of these in the brooks. 2. Tim's right here. Almost certainly crustacean, maybe callianassid (ghost shrimp) 3. Yep: ammonite. Possibly Placenticeras 4 & 5. Impression of some bivalve Link to comment Share on other sites More sharing options...
Plax Posted February 8, 2016 Share Posted February 8, 2016 am thinking your crab piece might be Linuparis (may not be spelled correctly) Link to comment Share on other sites More sharing options...
wetwilly Posted February 8, 2016 Author Share Posted February 8, 2016 Thanks, great info Carl. I am trying to understand the many diverse items that one can get out of the Brooks. They all seem to look like "something". Not sure of what a Linuparis is Plax, (looked it up briefly), but I found another similar item that could be associated. Thanks again.

erose Posted February 9, 2016 Share Posted February 9, 2016 There are a good variety of different crustaceans in the Cretaceous of those brooks. The "ghost shrimp" claws are the most common but larger material from crabs and lobsters show up. You will quickly learn to recognize that surface texture and even the smallest scraps will be easy to at least sort out as "crustacean." Link to comment Share on other sites More sharing options...

Bill This piece is one of the arm segments of a crustacean and I've always IDed these as callianassids. Link to comment Share on other sites More sharing options...
Plax Posted February 9, 2016 Share Posted February 9, 2016 The dark color and texture remind me of other Linuparus specimens I've seen from Big Brook. Couldn't opine on the claw and suspect that Carl is correct on that one. The callionassid claws will sometimes come in pairs. they have a pretty smooth texture.
