Frozen in time
by Lucy VanSwearingen
I was fortunate to collect this track on private land with the local geologist in Glen Rose, TX. It is illegal to collect fossils from public lands and in the Dinosaur Valley State Park--You have to have a Texas State Permit.
This track was made by a three-toed, sharp-clawed, two-legged meat-eating dinosaur called s theropod. Most of these prints (which are typically 15 to 25 inches long) are thought to have been made by Acrocanthosaurus, a 20-30 foot long carnosaur whose bones have been found in nearby areas.
these tracks are found in the Paluxy riverbed in the Upper Cretaceous (~ 110 million years old)
I am taking some liberty, as this track was in limey mud probably in a tidal flat or lagoon.
By the way...I am a geologist, who happened to be in Glen Rose watching my stallion win third place in the SW Reining Horse Futurity.
Now, aren't you glad you looked? As Stan knows, I like to photograph "the unusual"!

8 commentsCome on up to Colorado, if you want to photograph dino tracks in REAL sandstone.
Don't worry, this was a flagstone in the river. I did not chip it out.
I would LOVE to come out west and look at your dino tracks! I did fieldwork in Zion and Bryce (Utah) and loved it! So I never got near your dino tracks. I hear they are spectacular! One day........
And Robert, I did not even think of a lizard. What a terrific idea!
Thanks for looking!
I would love to go out and take photos with a geologist, I like geology but have no formal education.
