fossilchik2 Posted November 25, 2015 Share Posted November 25, 2015 This is my first time taking pictures of fossils so their quality isn't greatest! I can take more if needed, however it's pretty flat - only a top and bottom. ** Sorry my post isn't formatted very well!! ** I found this a few years ago while I was swimming in lake havasu. (Colorado river). I was snorkeling and it was under a few feet of water. It caught my attention because of the white spot and when I looked closer at it there was an impression in the white spot that resembled the wing of an insect or the wing bones of a very small bird. The rock it is on is dark grey and I can tell it was under water for a long time as it is smooth as a river rock. However, it doesn't seem like the kind of stone a fossil would ordinarily form in. I would really like to know if this is a fossil of some sort or if it is something else. Link to comment Share on other sites More sharing options...
Manticocerasman Posted November 25, 2015 Share Posted November 25, 2015 This is a horn coral. but I dont now the age of the fossil. growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 25, 2015 Share Posted November 25, 2015 Hello Lisa, I believe you do have a fossil there. The question is what? It could be one of two things, I think. I tried to enhance your best image, but it is still quite fuzzy. My initial thought was that it was a longitudinal cross section of a rugose, or "horn" coral. Imagine a cone shape lying flat, then water and sand sanding it down until there is only a little bit left. This is my first choice for an ID. The other thing it could be is the impression of a brachiopod. The creature may have died, leaving the shell embedded in the mud, and the impression that was later left was worn down in the same way as I explained above. The item is heavily water worn, so it may not be possible to to tell one way or another. Only extremely sharp pictures may be able to tell us which it is. Even then, it is quite likely that there isn't enough detail to be sure, one way or another,...to ID it any further, ...other to say it is an invertebrate fossil, and not an insect wing. Maybe some others will be able to see more than I can in the photos, so wait for some more responses.

TqB Posted November 25, 2015 Share Posted November 25, 2015 I think Tim and Kevin are right with longitudinal horn coral section. Tarquin Link to comment Share on other sites More sharing options...

I hope they're better but my photography skills are non-existant! Link to comment Share on other sites More sharing options...
