Scientists have discovered the stays of 4 species of dinosaurs, together with a megaraptor, in an inhospitable valley in Chilean Patagonia that has emerged over the previous decade as an necessary fossil deposit, researchers mentioned Wednesday.
The fossils have been present in Cerro Guido, in southern Chile’s Las Chinas valley close to the border with Argentina, and brought to a laboratory in 2021. The researchers mentioned they belong to dinosaurs that haven’t beforehand been recognized within the space.
“It is at all times tremendous thrilling in scientific phrases to seek out one thing that has not beforehand been found or described within the Las Chinas valley, the place we’ve develop into used to discovering new fossil stays,” Marcelo Leppe, director of the Chilean Antarctic Institute (Inach) which was a part of the analysis workforce, instructed AFP.
Inach collaborated with the College of Chile and the College of Texas on the expedition.
They recognized the stays — together with enamel and postcranial bone items — of 4 species of dinosaur together with the megaraptor, which belongs to the theropod household.
These carnivorous dinosaurs had raptor claws, small enamel for tearing, and enormous higher limbs which, in line with the analysis, put them on the high of the meals chain within the area, which they inhabited between 66 and 75 million years in the past, on the finish of the Cretaceous interval.
“One of many traits that allowed us to determine with nice confidence that they belong to megaratorids are, initially, that the enamel are very curved in direction of the again,” mentioned Jared Amudeo, a researcher with the College of Chile, in a press release.
Additionally they recognized two specimens of Unenlagiinae, carefully associated to velociraptors and which have a “novel evolutionary character, which might point out that this can be a new species of unenlagine or maybe a consultant of a distinct clade (group),” mentioned Amudeo.
Additionally they discovered stays of two fowl species: an Enantiornithe, probably the most various and plentiful group of birds of the Mesozoic; and Ornithurinae, a bunch instantly associated to present-day birds.
The scientists’ work was compiled in a research revealed final December within the prestigious Journal of South American Earth Sciences.
