reenie8888 Posted November 5, 2023 Share Posted November 5, 2023 I am selling my dad's estate and came across these. He had purchased for me as I collect rocks and seashells. I want to sell them to defray burial expenses but dont feel comfortable doing so without knowing whether these are "real." Anyone willing to advise me as to authenticity? Value? Here are 3 pieces. They are approx 5" wide each. The first appears to be a clam shell. The next two appear to be sediments with shells or shell impressions.Locations unknown. Any help much appreciated!

Tidgy's Dad Posted November 5, 2023 Share Posted November 5, 2023 I am sorry for your loss. Yes, they are real. The first one is an oyster from the family Gryphaeidae, I think. The others are, as you say, just fragments of shell in matrix and some impressions and holes where the original shells have dissolved away. 1 Life's Good! Tortoise Friend.

Fossildude19 Posted November 5, 2023 Share Posted November 5, 2023 The Forum does not provide monetary valuations. That said, you might be able to buy a coffee with the proceeds of the sale of these items.

DPS Ammonite Posted November 5, 2023 Share Posted November 5, 2023 The look like possible Cretaceous fossils from Texas. Exogyra for the giant bivalve and Cordova Shell Limestone for the piece with fossil molds. https://depositsmag.com/2016/07/07/urban-geology-monumental-geology/amp/ https://wap.stonecontact.com/cordova-shell-limestone/s15806#:~:text=Fossil-Rich Appearance%3A The defining,connection to Earth's distant past. 2 3 My goal is to leave no stone or fossil unturned.

reenie8888 Posted November 5, 2023 Author Share Posted November 5, 2023 Ty. Can you tell me what the white sediment with shell impressions are called? Do you know what any of them are called? Link to comment Share on other sites More sharing options...

erose Posted November 10, 2023 Share Posted November 10, 2023 The Cordova limestone is used for architecture in Texas. The typical slab of that material features the clam Trigonia. Link to comment Share on other sites More sharing options...
reenie8888 Posted November 18, 2023 Author Share Posted November 18, 2023 TY for the info. I think my dad may have bought these in Austin whennI lived there! Link to comment Share on other sites More sharing options...
reenie8888 Posted November 18, 2023 Author Share Posted November 18, 2023 Would anyone care to comment on these pictures. They are from the same box of fossils. Are they possibly Exogyra or maybe another genus in Gryphaeidae? The both measure about 4" long. The top specimen has deeper ridges than the bottom one. Any help appreciated!

DPS Ammonite Posted November 19, 2023 Share Posted November 19, 2023 Probably both Exogyra. The bottom one is broken and really worn making ID less certain.
