Zenmaster6 Posted February 25, 2019 Share Posted February 25, 2019 Hey, I posted my trip to California from Washington yesterday. I have now looked through my rocks and noticed that one of these rocks are different from the rest. I took a picture of the Buchia Bivalve in the first image, to show that it has a different shape and markings than the bivalves I found there. If anyone can give me a genus that would be great. Is this another shell or something more? Thanks guys Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted February 25, 2019 Share Posted February 25, 2019 Interesting. But still looks like a fragment of Buchia to me. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I respect that, but also, could you tell me how you came to that conclusion? The markings seem significantly more spaced out than the Buchia, the shape is more triangular. Could it be another species of Buchia? Link to comment Share on other sites More sharing options...

But there seems to be quite considerable species differentiation. Somebody else may know better than I. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Mike from North Queensland Posted February 25, 2019 Share Posted February 25, 2019 A photo of the broken end may help as this will give a cross section of the specimen. Further preparation may also help. Mike 1 Link to comment Share on other sites More sharing options...

Lets all hope I don't break it in the process Link to comment Share on other sites More sharing options...
Zenmaster6 Posted February 25, 2019 Author Share Posted February 25, 2019 Here it is mostly removed from the matrix Link to comment Share on other sites More sharing options...
Zenmaster6 Posted February 25, 2019 Author Share Posted February 25, 2019 I was thinking a Myophorella which lived in the Jurassic / Cretaceous Link to comment Share on other sites More sharing options...
Wrangellian Posted February 26, 2019 Share Posted February 26, 2019 Why did you remove it from the matrix? I don't see any change that would help with identification, and I thought it looked nice as it was. Anyway I'm not really sharp on my Jurassic and am not sure what either of them are so I can't help you at the moment. Link to comment Share on other sites More sharing options...

I wanted to show the shape of it as well. I agree it looked better in the rock :c Link to comment Share on other sites More sharing options...
Wrangellian Posted February 27, 2019 Share Posted February 27, 2019 I haven't seen shots from other angles, but it probably would have been sufficient for the edges to have been exposed a little more to show the full outline, and that may be all Mike was suggesting... Oh well! Link to comment Share on other sites More sharing options...
