Geobam Posted July 14, 2017 Report Share Posted July 14, 2017 Bonjour à vous, voici un spécimen étrange collecté dans des marnes drômoise au pied du Vercors. Si cela est un bivalve, quel en est le type? Merci d'avance pour vos réponses. Quote Link to comment Share on other sites More sharing options...
Next50MY Posted July 14, 2017 Report Share Posted July 14, 2017 Bivalve peut être mais moule interne et externe Quote Link to comment Share on other sites More sharing options...
Geobam Posted July 14, 2017 Author Report Share Posted July 14, 2017 Merci Next50MY, la partie avec les petits points alignés est vraiment atypique. Quote Link to comment Share on other sites More sharing options...
Lucailloux Posted July 14, 2017 Report Share Posted July 14, 2017 Peut-être un bryozoaire encroûtant ? Quote Link to comment Share on other sites More sharing options...
Next50MY Posted July 14, 2017 Report Share Posted July 14, 2017 Non car les orifices sont alignés a contrario des bryozoaires Quote Link to comment Share on other sites More sharing options...
