Track Lighting: Dinosaur "Dance Floor" in Bolivia -- Over 5,500 Footprints

       These late Cretaceous dinosaur footprint fossils on a near-vertical outcrop in Bolivia represent at least 294 different dinosaurs (and, at least 8 species) with over 5,500 footprints.

       The paleontological site, known as Cal Orck'o, is located a few kilometers south of Bolivia's Sucre city center.

       Although, I imagine there was more chasing than dancing on this "Dinosaur Dance Floor," it is an exquisite find, uncovered in 1994, in a cement quarry. Both carnivores and herbivores are represented. This longest set of tracks is over 350 footprints! Parco Cretacio is now open to the public; 68 million years in the making!

     The tracks were likely created by a juvenile Tyrannosaurus rex, nicknamed Johnny Walker ;-).

     And these footprints were likely made by an Iguanodon.

      

      The extent of dinosaur footprints on over 25,000 square meters is being studied by Christian Myer and Martin Lockley (of Colorado Morrison Dinosaur Ridge footprint fame). The largest prints are 3 feet long.

     Tectonic uplift moved these fossil footprints to a 70 degree plus angle. Pretty wild dance party ;-).

Have you been to see the Bolivian dinosaur footprints? Have you seen dino tracks in the Connecticut River Valley or elsewhere?

{The Colorado Dinosaur Ridge footprints are quite spectacular, but are not nearly as extensive as the Bolivian tracks.}
