Creek - Don Posted September 29, 2019 Share Posted September 29, 2019 Found a curious circular thing on the bottom of the creek. It looks like a circular coral that I saw picture on the Internet once. Creek bed is around middle cretaceous period. Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 29, 2019 Share Posted September 29, 2019 Looks like Rudist material.

JohnJ Posted September 30, 2019 Share Posted September 30, 2019 If it is Austin Chalk (Kau), you are likely seeing the remnants of giant Inoceramus clams. The calcitic fragments are typical of these large clams. 4 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Creek - Don Posted September 30, 2019 Author Share Posted September 30, 2019 Most of the giant clams located here in Dallas Austin Chalk are like like this on the picture. One I found on the creek bed are more odd shaped though. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted September 30, 2019 Share Posted September 30, 2019 5 hours ago, JohnJ said: If it is Austin Chalk (Kau), you are likely seeing the remnants of giant Inoceramus clams. The calcitic fragments are typical of these large clams. John is right. Inoceramids (some have divided Inoceramus into many genera), have a shell composed of calcite prisms that are normal to the shell surface. See: http://oceansofkansas.com/Inoceramids.html “According to Sowerby 1823, Inoceramus means "fibrous shell," describing the prisms that are visible on the edge of shell fragments.” 2 My goal is to leave no stone or fossil unturned.
