Overview of the Discovery
Brazilian scientists have identified a new species of giant dinosaur named Dasosaurus tocantinensis, which has significant implications for understanding the prehistoric connections between continents. This discovery was detailed in the Journal of Systematic Palaeontology and highlights the existence of land routes that once linked parts of South America, Africa, and Europe approximately 120 million years ago.
Key Details of the Fossil Discovery
The fossils of Dasosaurus tocantinensis were uncovered in 2021 during infrastructure work near Davinopolis in the northeastern state of Maranhão, Brazil. The research team, led by Elver Mayer from the Federal University of the Sao Francisco Valley, found a femur measuring about 1.5 meters (59 inches). This measurement allowed researchers to estimate that the dinosaur stretched roughly 20 meters in length, marking it as one of the largest dinosaurs discovered in Brazil.
Leonardo Kerber, a paleontologist at the Federal University of Santa Maria (UFSM) who contributed to the research, remarked on the excavation process, stating, "As the excavation progressed over the days, we began to see the evidence of that huge bone, which is the femur." He emphasized the significance of this find, noting, "Today we know Dasosaurus is among the biggest dinosaurs ever found in Brazil."
Evolutionary Significance
The analysis conducted by UFSM indicates that Dasosaurus tocantinensis is closely related to Garumbatitan morellensis, a dinosaur previously described in Spain. This relationship suggests that their lineage may have originated in Europe and dispersed into what is now South America around 130 million years ago, likely through northern Africa, prior to the full opening of the Atlantic Ocean.
Implications of the Discovery
The identification of Dasosaurus tocantinensis not only enriches the fossil record of Brazil but also provides insights into the biogeographical patterns of dinosaur evolution. The discovery reinforces the idea that land connections existed between continents during the Early Cretaceous period, allowing for the migration of species across what are now separated landmasses.
Official Statements & Responses
The research team has expressed excitement about the implications of their findings. Elver Mayer stated that the discovery enhances our understanding of dinosaur diversity and distribution during the Cretaceous period. The collaboration among Brazilian institutions has been pivotal in advancing paleontological research in the region.
