Dreamsausage777 Posted August 24, 2018 Share Posted August 24, 2018 Hello I just joined so first I will say hello my name is Julien I love in Colorado. I just acquired a new geode with a fossil iside of it. I was wondering if someone could identify what kind of geode it is and how rare it is to have one whole like this? Thank everyone for their help in advance I’m sure the members of this site are pretty smart. Link to comment Share on other sites More sharing options...

ynot Posted August 24, 2018 Share Posted August 24, 2018 This is a strange one. I think it is a septarian nodule. Not a fossil. The whitish spot is possibly a shell, but need better close up of it to tell for sure. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Fossildude19 Posted August 24, 2018 Share Posted August 24, 2018 I'd say that the white parts are bivalve shells.

ynot Posted August 24, 2018 Share Posted August 24, 2018 I think this is the first septarian with a fossil in it that I have seen. Very unusual. Nice find. Darwin said: " Man sprang from monkeys."

Dreamsausage777 Posted August 25, 2018 Author Share Posted August 25, 2018 Sweet I am going to do some more research I appreciate the responses so far. Ynot I will get you a better picture. I am trying to take it apart as least as possible since it fits together so nicely. Link to comment Share on other sites More sharing options...

I’ve got septarian a with fossils in them. This one is my favorite with part of a fossil in it. It is a septarian that broke open and eroded away leaving a thin waffer of yellow calcite with a shell fragment under it. The calcite looks like a flower petal from the side. I found this with some very big septarians there too. Link to comment Share on other sites More sharing options...

Max-fossils Posted August 25, 2018 Share Posted August 25, 2018 18 hours ago, Fossildude19 said: I'd say that the white parts are bivalve shells. Agreed. These are most definitely fossil bivalves. Sweet!!! At first, I would've said that they were steinkerns, but looking more closely you can notice that the little "teeth" at the bottom of both shells. These are very similar to those you'll see in the Donax genus, especially the species Donax vittatus (hence why it's called "zaagje" in Dutch, meaning "little saw"). Your shell is definitely not a Donax vittatus (because of shape, age and location), but the presence of those little "teeth" does mean that your fossil is not just the steinkern but actually the shell itself (which IMO is much better ). Does anyone know how to find out the age of a septarian nodule like this one? Max Derème "I feel an echo of the lightning each time I find a fossil.
