moments in focus…

100+ million years old!


It’s hard to believe that Texas was once covered by water. The Glen Rose formation was deposited during the periodic retreat and advancement of a large shallow sea, which may be considered the ancient gulf of Mexico. The deposits represent low subtidal to supratidal environments and typically exhibits alternating beds of hard limestone and softer marl (limy clays and shales). (source: the internet)

As my husband I were enjoying a day at the lake (Lake Travis, Austin) we discovered many fossils.   The fossil in this image is approximately 110 million years old.  Hard to believe I can hold something in my hand that is that old!  Amazing.

Here are a few Lake Travis facts taken from the LCRA (Lower Colorado River Authority) website:

Lake area: 19,297 acres

Elevation when full: 681 feet above mean sea level (msl)

Historic high: 710.44 feet above msl on Dec. 25, 1991

Historic low: 614.18 feet above msl on Aug. 14, 1951

Target operating range: at or below 681 feet above msl

Today: 639 above msl

100-year flood level: 722 feet above msl

Mansfield Dam Spillway: 714 feet above msl

Public Boat Ramps: 11 are located on Lake Travis, only one boat ramp remains open today and will close ate 632 msl.

    • thank you both for your nice words. This was one of those lucky pictures. I polished my dining room table and put the fossil on it, outside and overhead light did the rest.
