<dinofyi-dinosaur slug="leyesaurus-marayensis"></dinofyi-dinosaur>† Maraapunisaurus fragillimus was a titanosauriform sauropod known from a single enormous vertebra discovered in the Morrison Formation of Colorado (~1870s) and subsequently lost. Extrapolations suggest it may have reached 30-40m, potentially the largest land animal ever.
Time Period
Leyesaurus marayensis lived during the Jurassic Early period of the Mesozoic Era, approximately 201.4 to 174.7 million years ago.
After the Triassic-Jurassic extinction, dinosaurs rapidly diversified and became the dominant land vertebrates. Early sauropods and theropods began to evolve larger body sizes.
