austinswamp Posted January 25, 2017 Share Posted January 25, 2017 I found this near Cottonmouth creek, 8 miles south of Austin. Some material throughout the creek looks to be lithified beach sediment. The extinct volcano called " Pilot Knob" is said to have erupted roughly 80 million years ago. The rock is about 2.5" inches long. Link to comment Share on other sites More sharing options...

ynot Posted January 25, 2017 Share Posted January 25, 2017 Looks like a concretion of layered silt/sand stone. More pictures may help to get a better idea of what it is.

Vieira Posted January 25, 2017 Share Posted January 25, 2017 Do not looks like a fossil to me. My guess it's geologic. Link to comment Share on other sites More sharing options...

That correlates with your possible ID. Link to comment Share on other sites More sharing options...
