I don’t have too many tylostoma gastropods, but I found a few yesterday that include the biggest one I’ve found in one piece. Small hemiaster and heteraster echinoids galore as well. The big Tylostoma will replace one of my current “keepers” in my collection. Tarrant county, TX near downtown Fort Worth. The others are anchura(?)

Goodland echinoids and gastropods-Ft Worth TX
Shaun-DFW Fossils posted a topic in Fossil Hunting Trips
I went back to cover more ground on my massive goodland exposure and found a bunch of additional hemiaster and heteraster echinoids. These are much smaller than macrasters, but I found two relatively large ones. I like the texture due to the bumps where spines once were. Tylostoma and other gastropods can be found there too. I’ll work on blasting the sand off. Tarrant county, TX in Fort Worth.- 5 replies

GlenRose Formation 105 - 115 MYA Found near roadcut in San Antonio Im thinking Tylostoma but I'm not sure. Maybe someone can chime in? Also check out these echinoids I found there as well (and the hermit crab claw)

My family just returned from a three day, New Years visit to Boerne ("Bernie"), Texas. On our way home, we stopped of by a construction site on the northwest side of San Antonio. I believe it was Glen Rose Formation. We found some nice specimens, including gastropods, brachiopods and even some echinoids. The largest specimens are shown below. The scale is in centimeters. My question is, are these specimens Tylostoma sp. or Lunatia pedernales? I've seen them identified on TFF as Tylostoma. But in the HGMS Texas Cretaceous Gastropods book, they describe Tylostoma of similar sizes as having a spire 50% of the total length of the shell. However, the Lunatia pedernales is described as having a spire 25% of the total length. I would just like some clarification. I'm leaning toward Lunatia, but I'm easy to persuade by those with far more knowledge and experience... Thanks in advance for your help.
