RogerN Posted November 16, 2017 Share Posted November 16, 2017 A lower Cretaceous Tylostoma tumidum, yes or no? I obviously did a little research on this snail. I picked this up is a in a pile of rocks from a quarry some where in Texas. Even with a chip off the top spire it's twice the size of a couple similar snails I've picked up.

Herb Posted November 17, 2017 Share Posted November 17, 2017 I agree with the genus , hard to tell the species with a partial specimen "Absence of evidence is not evidence of absence"_ Carl Sagen No trees were killed in this posting......however, many innocent electrons were diverted from where they originally intended to go.

erose Posted November 17, 2017 Share Posted November 17, 2017 Definitely Tylostoma. I often have to have a handful from a site in hand before I am willing to place a species name on them. In the Glen Rose you can have a handful of species in the same strata. Link to comment Share on other sites More sharing options...
