Quer Posted February 16, 2018 Share Posted February 16, 2018 Hi, I found those pieces in a Maastrichtian limestone strata of the SE of the Pyrenees. Size (large): 1 - 25 mm 2 - 37 mm 3 - 39 mm My guess is genus Ceratostreon, and specifically Ceratostreon pliciferum for Nr.3. Thanks, Link to comment Share on other sites More sharing options...
MikeR Posted February 16, 2018 Share Posted February 16, 2018 I don't know about the species but it sure looks like Ceratostreon from the Texas Albian.

abyssunder Posted February 16, 2018 Share Posted February 16, 2018 There are very nice Beekite rings on the specimens (visible mostly in the last picture).

Quer Posted February 17, 2018 Author Share Posted February 17, 2018 Thanks a lot MikeR and abyssunder. Beekite rings appear from time to time in fossil shells around here, but I didn't know what they are. Thanks to you I've learned one thing more.
