(Julia) Posted January 4, 2017 Share Posted January 4, 2017 Please take a look at this. It's about 8"x4"x5"... guessing. But extremely interesting. I found it in a creek bed here in Round Rock TX. What is it? Link to comment Share on other sites More sharing options...

Fossildude19 Posted January 4, 2017 Share Posted January 4, 2017 Rudist, I think. Wait for some more opinions though.

JohnJ Posted January 4, 2017 Share Posted January 4, 2017 It's a fragment of an Upper Cretaceous rudist known as Durania. 9 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

John, For the ones who do not have the faintest idea of what a rudisted/rudist is perhaps a nudge in the right direction might help. Strange as it may be, Rudists are associated with or part of the family of clams aren't they? Jess B. Link to comment Share on other sites More sharing options...

I personally have information, but many others though they have heard and have and seen rudistids their intrest in them is limited. I myself as an adolescent thought of them as corals. It was not till I had grown up that I learned of the unique way in which these "clams" developed. My point is some people just do not go beyond the name/type of specimen in question. I recently was talking with another collector, who did not know what the difference between a rugosa and a rudistid. Easy for some, confusing for others who may be mentally challenged. Open, honest and specific answers can lead some others to understanding things that to them are confusing. Thanks again for your input. Howdy John.

I remember when I first discovered fossils and started collecting on the side when I was more interested in minerals. I didn't really care what they were called. They just looked neat. Then when I decided to get more serious about it I noticed how complicated it could get, much more so than surface identifyng minerals. It was really frustrating at first to be able to wrap my head around all that. Not just ids, but all that stratigraphy and geology and stuff. Then I really got interested in it all, and that was the point where I really started learning because I really wanted to. 2 Greetings from the Lake of Constance.

bone2stone Posted January 8, 2017 Share Posted January 8, 2017 I was born into getting outside digging the the stuff below my feet. I do not remember finding my first real collectable fossil or my first artefact (arrowhead) Going to school, as I grew, my teachers always expected a show and tell. Thing about it was they would often have to tell me what it was that I found. My school projects often involved fossils. I do not have many specimens from those memories, most I gave to the school. Some still on display in the science labs to this day. Well I have effectively led this thread astray long enough. Everyone have a good night. Jess B.
