Even though some of the largest dinosaurs get the most attention, dinosaurs actually came in a variety of sizes. This past week paleontologists announced two discoveries that emphasize just how large, and how small, some dinosaurs were.
From Plagne, France came the announcement of the largest dinosaur footprints yet discovered. Naturalists Marie-Hélène Marcaud and Patrice Landry found the tracks back in April, at which point paleontologists Jean-Michel Mazin and Pierre Hantzpergue from the Université Claude Bernard Lyon went out to have a look. They discovered that the 150-million-year-old tracks were made by enormous sauropod dinosaurs, the largest probably stretching over 85 feet and weighing more than 40 tons.
Contrast that with a find announced yesterday in the
I wonder how many of the tiny theropods could have fit into just one track made by the enormous sauropod!
