A clearer photo of the exterior texture of the ball will convince me that this is an algal ball, Porocystis sp. that is found in Early Cretaceous formations such as the Glen Rose. 3 My goal is to leave no stone or fossil unturned.

Carlitos Posted September 15, 2020 Author Share Posted September 15, 2020 I did a little more poking around on the internet and I believe these are Crinoids. The cup or Calyx portion of the animal from which arms attach. Link to comment Share on other sites More sharing options...
grandpa Posted September 15, 2020 Share Posted September 15, 2020 1 minute ago, DPS Ammonite said: this is an algal ball, Porocystis sp. that is found in Early Cretaceous formations such as the Glen Rose My thoughts exactly. BTW, Johnson City is in Blanco Co. Llano Co. is NW of Blanco Co. The geology of Llano County (Llano uplift area) is too old to support finding a lower Cretaceous Fossil such as Porocystis. So either the location is wrong (likely) or the ID is wrong (I think not). 3 Link to comment Share on other sites More sharing options...
