davidcpowers Posted January 18, 2019 Share Posted January 18, 2019 Hey there I was prepping a plate of Baculites when I noticed what looking like a bone. At the time int was hidden under a crust of calcite. After removing the calcite I now need to gather ideas on what kind of bone this maybe. So, I am looking for some ID help. 2 Link to comment Share on other sites More sharing options...
abyssunder Posted January 18, 2019 Share Posted January 18, 2019 maybe a partial vertebra?

davidcpowers Posted January 18, 2019 Author Share Posted January 18, 2019 Thank you Abyssunder it maybe a vertebra. It is about 4cm square. It is missing sockets that could explain jointing. Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 18, 2019 Share Posted January 18, 2019 Bit of fish skull would be my guess. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

davidcpowers Posted January 19, 2019 Author Share Posted January 19, 2019 from what I see the left side is a smooth curved edge. The bottom edge is concave curved edge. The top may mirror the bottom. But that is missing. It could be a part of a fish skull. Link to comment Share on other sites More sharing options...
uncoat Posted January 19, 2019 Share Posted January 19, 2019 Hey there, it looks like a worn fish vertebra to me. Fish vertebra have a distinctive "Hour Glass" shape to them. The bone in your pictures has a very distinct "X" shape that shows when a fish vert is worn in half. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted January 19, 2019 Share Posted January 19, 2019 10 hours ago, davidcpowers said: The long silvery objects look more like clams than Baculites Do you see any septa in them? Similar clams such as Gervilliopsis occur in north Texas Cretaceous rocks: http://www.thefossilforum.com/index.php?/topic/74930-help/ My goal is to leave no stone or fossil unturned.

davidcpowers Posted January 19, 2019 Author Share Posted January 19, 2019 Hi Collections Curator, This plate is roughly 18 inches wide and 12 inches tall. I am sure these are baculites. Cross section is egg shape. Those in a little better condition show suturing and decorative elements. Those found near the telegraph formation are usually in better condition. The telegraph Formation is about ten to fifteen feet up from the strata where I removed this hash plate. About 60 miles east in the bear paw shale the baculites will be larger and in better condition. I have found a few clams. They tend to be small with badly decomposed shells at this level in the mudstone. Higher up they are a little larger around 6cm and in better condition. This is the first piece of bone I found in with my usual invertebrate fossils. Link to comment Share on other sites More sharing options...

davidcpowers Posted January 19, 2019 Author Share Posted January 19, 2019 Hey Old Bones and Uncoat, After Uncoat brought up fish vertebra I did some checking this morning before heading to work. I'm incline to go with fish vertebra. Thank you Old Bones and Uncoat for your help. Link to comment Share on other sites More sharing options...
