Crewof72 Posted January 19, 2018 Share Posted January 19, 2018 I'm a new member, so thanks for accepting me. My family and I have hunted for fossils, arrow heads, and sharks teeth for many years. It has been a way to pass the time on hunting leases and on the beach. It has always been a hobby, we have never worried about identification of any particular piece...until recently. Being retired, I started going through our collection, just for the heck of it. I found this piece that we have always been curious about. It was found in a creek bed on a ranch near Sonora, Texas, in northern Schleicher County. It was found 6-7 years ago, we leased the property for deer hunting for four years. With all that said, I posted pictures of it on a FB group. It has been called a "cone in cone" structure, an unknown type fossil, and a man made fake. The post on FB has been entertaining to say the least. One person responding recommended this group so here I am. I am in the Houston area so I would be willing to take it somewhere for a better look. Thanks in advance for any help you can offer. Link to comment Share on other sites More sharing options...
Al Dente Posted January 19, 2018 Share Posted January 19, 2018 Might be an imprint of Rastellum. Here's a link to a picture: http://www.northtexasfossils.com/bivalvia/dentureclam3.jpg 5 Link to comment Share on other sites More sharing options...

Aurelius Posted January 19, 2018 Share Posted January 19, 2018 The pictures aren't that good - it would help if you rotated either the rock or the camera, so that the object took up the whole frame, rather than being a small part of it. Link to comment Share on other sites More sharing options...

ynot Posted January 19, 2018 Share Posted January 19, 2018 The rock looks like calcite to Me, could the "cone" shapes be dog tooth spar that has weathered? Take a small piece (from an unobtrusive area) and crush it then place a drop of vinegar on it to see if it fizzes. I think it is a non fossil rock. 1 Darwin said: " Man sprang from monkeys."

abyssunder Posted January 19, 2018 Share Posted January 19, 2018 (edited) I suppose, the white little concentrically arranged cristal forms are beekite rings and that might be the reason why the material doesn't react to vinegar. I just find Sophie's older post suggesting similarities.

M Harvey Posted January 19, 2018 Share Posted January 19, 2018 Looks suspiciously man made. Reminds me of kiln cones used in pottery. A potter will line them up like dragon teeth embedded in a piece of clay and place them in the kiln during firing. They melt when the proper temp is reached. Fired clay would not fizzle with vinegar. I'm not saying that's what your specimen is without examining it. Just throwing this idea into the mix. 1 Link to comment Share on other sites More sharing options...

Miocene_Mason Posted January 20, 2018 Share Posted January 20, 2018 For some reason I have a feeling it’s a mineral/geological product. However, My feelings are known to be wrong from time to time. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Will it scratch glass? Can You see if there are different rock types making up the whole stone? I think @abyssunder has it right with beekite. Darwin said: " Man sprang from monkeys."

KimTexan Posted January 20, 2018 Share Posted January 20, 2018 I’m glad to see you got it posted here and have gotten some constructive feedback. There was part of it that I wanted to see a closer up pic of. This is a cropped portion of a pic you had on FB. I can’t tell if it is weird weathering or a tiny fossil, but it looked like a small fossil or fragment of one. See the red arrow below. Could you take a pic zoomed in on that? I don’t know what you use to take pics. I use my cell phone. I bought a little clip on wide angle/macro lense that works reasonably well for the price on Amazon for under $15 I think.

Thanks. This rules out beekite. Some rocks have to be looked at in hand to be sure of what they are. I suggest taking it to the geology department of a local university or museum.

Tidgy's Dad Posted January 23, 2018 Share Posted January 23, 2018 I don't think it's Rastellum. Here's one of mine and it doesn't match for me. Oh, it won't upload images. Terrific. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Max-fossils Posted January 23, 2018 Share Posted January 23, 2018 @Tidgy's Dad I'm having the same problem, meaning I can't show my Rastellum either. And honestly, (sorry for bringing a destructive ID instead of a positive) though I can clearly see how it could be Rastellum imprint (making it an ichnofossil), I just don't think that could be it! Never seen marks so distinct made by the side of a bivalve, unless the actual bivalve just got taken away from the rock. But that means that in that time it wouldn't have had time to grow crystals there, as it wouldn't have had enough time. So I am just thinking on a timing point of view, not really geologic, but I think my argument does make sense. This sure is a very intriguing piece!!! Looking forward to seeing other suggestions!
