Lower Cretaceous Vertebrate Fossils of Central Texas

Recently a fellow collector was trying to get some help with a small shark tooth from the Glen Rose Formation (Albian) and the discussion proved limited by the lack of good references for shark and other teeth in the lower divisions of the Cretaceous of Central Texas. So this album will highlight the small collection of teeth and bone I have accumulated from the Glen Rose and Walnut Formations, Trinity and Fredericksburg Groups respectively, both Albian (Lower Cretaceous). Take a look and please give me feedback, especially if you have a question with my identification.
