paul-waxahachie Posted September 17, 2013 Share Posted September 17, 2013 Piece of a creekbed Waxahachie, Texas. Look closely you can see the fossil imprints of dozens of inoceramid clams on this one piece of limestone. Link to comment Share on other sites More sharing options...
Ridgehiker Posted September 17, 2013 Share Posted September 17, 2013 Wow. Those are big. This genus of bivalve must have dominated a wide area at one time. Every so often I've come across beds of them when driving through remote parts of Utah, Montana, etc. and they get the collecting juices flowing. Sometimes they seem to be the only fossil present when in layers. Other times, when in big nodules, fun to crack them open and hope to discover ammonites, etc. Link to comment Share on other sites More sharing options...
jpc Posted September 17, 2013 Share Posted September 17, 2013 In Wyoming, if you find layers of Inoceramids... start looking for their neighbors the ammonites. Link to comment Share on other sites More sharing options...
paul-waxahachie Posted September 17, 2013 Author Share Posted September 17, 2013 There are single inoceramids fossils as large as a hoola hoop in that same creek. It is walking distance from my house. A University team from Poland spent a a few months onsite studying them. Link to comment Share on other sites More sharing options...

A University team from Poland spent a a few months onsite studying them.That sort of make up for your tiny deer.I've never seen Inoceramids in our Cretaceous bigger than 6 inches or so. The same with those in The Pierre Shale in the locale I collect in Montana. Placenticeras and Baculites ammonites get big but not the gastropods or bivalves.

Auspex Posted September 18, 2013 Share Posted September 18, 2013 The "Flat Clams" definitely had their day! Some of the beds in Kansas are practically made of their broken shards.

paul-waxahachie Posted September 18, 2013 Author Share Posted September 18, 2013 One of the more common fossils for sure. I will go to the creek and get a photo of one of the larger inoceramids tomorrow night. I didn't know the larger "fat clams" were uncommon in other States.

Ridgehiker Posted September 19, 2013 Share Posted September 19, 2013 Thanks. That's incredible. The Brontosaurus of bivalves. One wonders what variables in an ecosystem encourages supersize evolution.. Link to comment Share on other sites More sharing options...
Roz Posted September 19, 2013 Share Posted September 19, 2013 I had no idea they were that large in that area.. Welcome to the forum! Link to comment Share on other sites More sharing options...
BobWill Posted September 19, 2013 Share Posted September 19, 2013 We saw some that big on the Labor Day field trip DPS and MAGS shared in Cooke County Texas. Most were the same size as your first image but some were huge. Link to comment Share on other sites More sharing options...
Ludwigia Posted September 19, 2013 Share Posted September 19, 2013 We get some really humongous ones in the German cretaceous as well. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
