Gatra Vonresto Posted September 26, 2014 Share Posted September 26, 2014 Hello everyone. I have a new fossil. It is found in the field in Java. Some people told that it is an ammonite fossil. Maybe my friends here have more advanced knowledge about it, I would very glad to listen. Respectfully yours, Gatra Link to comment Share on other sites More sharing options...
Carl Posted September 26, 2014 Share Posted September 26, 2014 I'm going to call this one a snail. Link to comment Share on other sites More sharing options...
Ludwigia Posted September 26, 2014 Share Posted September 26, 2014 (edited) Yup. That is definitely a gastropod inner mold and a nice one at that. No ammonite.

Auspex Posted September 26, 2014 Share Posted September 26, 2014 I agree; it seems like an internal mold, and there is no sign of the chamber walls that an ammonite would have.

tmaier Posted September 26, 2014 Share Posted September 26, 2014 Possibly a Maclurites gastropod. Big one too... http://www.google.com/images?hl=en&q=Maclurites&gbv=1&sa=X&oi=image_result_group&ei=ONklVLu6LMSfyAS9yYL4Cw&ved=0CBQQsAQ Link to comment Share on other sites More sharing options...
FossilDAWG Posted September 26, 2014 Share Posted September 26, 2014 The whorl shape of this snail is quite different from Maclurites. The spire is too high (it isn't flat enough on top), and in Maclurites there are fewer whorls and they are much broader, flat on top, and are widest at the shoulder not 1/3 of the way down. Also in Maclurites the length of the shell (top to bottom) is about 1/3 of the width, which is the opposite of the specimen here. Don 1 Link to comment Share on other sites More sharing options...
