Since I asked it, this isn't a dumb question (is older up or down?)
SteveE posted a topic in Questions & Answers
As they said in school the only dumb question is the unasked one. So here goes... Instead of wasting field time fumbling around trying to figure this out, could someone please tell me how to read these sorts of section descriptions? Is the top of the printed list the top of the rock layer or the bottom? -
In my attempt to self educate myself, I am tring to find as much information on the Texas Cretaceous fossils I find. I am a bit confused about the scientific notation of genus species. For example, in much of the literature, there will be a name in parenthesis : like Pecten (Neithia) texanus or Trochus (Tectus) texana. (examples from the Studies of Some Comanchean Pelecypod paper). And in the Field Guide to Fossils of Texas, Mesalia (Turritella) seriatim-granulata and Gyrodes (Sohlella) spillmani. What does that mean? Is Pecten the proper name or Neithia? Is it Mesalia or Turritalla? Or is it both? Or if there is a question mark after the genus - like Cerithium? barionnenne or Pseudomelania ? pupoides (Both examples from the Studies of Some Comanchean Pelecypod paper). Are they just not sure if that is the proper Genus and leaving it open to interpretation and further study? Any help is appreciated!
