Geology/Unknown fossil


I found a possible fossil in central Texas which is known for marine life during prehistoric times. It is shaped like a tooth but I don't know if it is one. If it is a tooth, the organism would've been carnivorous and the possible fossil measures 1 cm in length by a half a cm in width. The color of this possible tooth is dark brown. Based on the description, is this most likely a tooth? If it's not, would you know what else it could be? Thanks so much for your time!  I'm sorry about not having a picture to go with the question. For some reason, I took a picture of it and I had trouble uploading it.

Hi Tyler,
Sorry but without an image it is just impossible to tell what you have.  There are fossil corals that look just like a large tooth, erosional features can create tooth-like specimens.  Some minerals can have that kind of shape.  If you can send a picture we'll have a good chance of telling what you have.
There are a couple of alternatives.  Take it to the Geology department of a local University or college, they are usually more than happy to help.  Also, a local rock club can be very helpful.  I have found that collectors can be very knowledgeable about the rocks and minerals in their area.  They should be found on the Web.

Hope this helps.

I can answer any general geology question (rocks, minerals, stratigraphy, geomorphology etc.). My expertise is in the geology of the Michigan Basin, PreCambrian, Paleozoic and Recent. I can answer questions concerning mining and petroleum exploration and production and the laws concerning those activities. I can also answer questions concerning stratigraphy of the Michigan Basin. I will also answer questions about mineral and rock collecting in the Basin. I won`t be able to answer many specific questions on hydrology, geophysics or geochemistry. I may be able to answer very general questions in those venues.
