#chirotherium

A picture of my chirotherium trackway site. Everything in front of the truck has been excavated. The truck is on the rocks of the lowest track layer. Behind the truck some of the second upper track layer is uncovered but not excavated. The leading edge of each layer goes from solid rock to a section of these loose individual tracks which I call Rex chunks - separate tracks from Chirotherium rex. The time period between the two layers could range from a couple hundred to maybe a thousand years, so very close in time.

Artwork created by Joshua Ballze from the Indigenous Peoples Museum in Prescott AZ. I’ve donated some indigenous artifacts and some fossil tracks to the museum and he gave me these amazing drawings of the critters associated with my tracks.

Some of my chirotherium tracks. The clip is 6” for scale. Middle Triassic, Moenkopi Formation, 240 million years old.

Chirotherium left rear track in red. Two partial rotodactylus tracks in blue. 240 million years old. The fifth digit on the chirotherium looks like thumb but is not actually a thumb. It is on the outside of the track. The rotodactylus has five toes but but frequently only three show up in tracks. Middle Triassic. Moenkopi Formation.
