treasured pasts Posted August 1, 2010 Share Posted August 1, 2010 I'm a rank amateur at identifying fossils and need some help with yesterdays finds including what to look for to help ID. Any help is appreciated. I think this is a straight Ammonite or maybe a bone fragment These are various interesting shaped finds. The red one on the bottom has interesting patterns and appears to have some shell attached like a conglomerate. Giant Clam? - Nice curl on it. Appears to be half a vertabrae from maybe a fish. Both sides are flat. Concave on one flat side. Lots of oyster shells etc. I can take closeups if anything looks interesting. Man was it HOT out there!!!

danielp Posted August 1, 2010 Share Posted August 1, 2010 Number 1 may be a baculite section and # 3 looks lime an exogyra ponderosa? Oyster Link to comment Share on other sites More sharing options...

Oyster In the last picture is a "tooth shaped item. It isn't a tooth but maybe part of an ammonite. It is covered with those oak leaf type designs.

It is covered with those oak leaf type designs. may be a fragment from a pachydiscus paulsoni ammonite. the pattern is called a "suture" pattern.

Auspex Posted August 1, 2010 Share Posted August 1, 2010 I kinda' like "oak leaf design" ; very descriptive.

treasured pasts Posted August 2, 2010 Author Share Posted August 2, 2010 (edited) I kinda' like "oak leaf design" ; very descriptive. Flowery descriptions are so much fun! It did draw the right picture anyway. I work in medicine. You'd have thought suture would have come to mind.

tracer Posted August 2, 2010 Share Posted August 2, 2010 i believe the suture patterns are where the original aragonite of the shell joined together in sections as it formed. the patterns generally speaking got more complex as time passed and are used both to help id particular ammonites, but also to differentiate between ammonites and the earlier, similar critters. i like finding ammonites with those patterns showing, and sometimes you find them with sections laterally shifted along those junctures and it's like a set of little raised, ornate "steps" on the side of the fossil...
