Archaeologists have discovered a record number of fossilized dinosaur footprints along an ancient coastline in Bolivia, according to a new study. Led by Raúl Esperante from the California Institute for Earth Science Research, researchers documented approximately 16,000 fossilized footprints from theropod dinosaurs (three-toed, two-legged predators) at nine study sites within the «Carreras Pampas» dinosaur footprint site, located in Torotororo National Park in central Bolivia. In the study, published in the scientific journal «PLOS Biology», the researchers stated that «data from 1,275 footprints were collected and analyzed, forming a detailed picture of the distribution of dinosaur sizes and behaviors, including turning, tail-dragging, and swimming». The footprints range in length from less than 10 centimeters to over 30 centimeters. According to the researchers, the diversity of footprint sizes and patterns suggests that a variety of creatures left their tracks at the site.
