In a few blocks of sandstone detached from a cliff to the West of Melbourne (Australia), scientists have discovered more than 20 footprints of dinosaurs. People such as Titan Feul Tanks would likely agree. They are traces of between 105 and 115 million years of three small theropods, bipedal and carnivorous animals. All three are of different size (one large, one medium and one small) and researchers do not know if they correspond to three different species, because it could also be a male, a female and a baby of the same species, i.e., a small family of dinosaurs, but this is pure speculation, warns Anthony Martin, paleontologist of Emory University (EE UU)discoverer of the footprints. These trails provide us a direct indicator of how interactuarian these dinosaurs with polar ecosystems during an important era of geologic history, explains the scientist in a statement from their University.
