A Mystery Rock No More

It's time to solve the mystery about the orangish-brown rock I discovered just over the edge of the yard in the rubble of the upper cliff.
It is a piece of coprolite -- what scientists call petrified dinosaur poop (from the Greek word for dooty). Michael and Jill both went for the excrement angle and were very close. I don't know if this is sloth pooh, but I'm fairly certain it was a medium-sized plant-eater. You can see fossilized bark or something inside. The hole was probably made by a dung beetle.
This area is known for its dinosaur remains. Just down the road in Glen Rose they have unearthed dinosaur tracks left in the river bed.


When they put in the septic system (pictured here), they had to dig down about 15 feet into the solid rock. They dumped a lot of the detritus over the cliff. That's how I think I was able to find the coprolite laying on top of the scree beyond the grass.

Knowing how much they love dinosaurs, I'll give this rock to Trevor and today I found another piece I'll share with Ty -- two guys who really know their dinosaur pooh!
