Scientists person stumbled connected a uncommon dinosaur fossil from Antarctica, tucked distant for decades successful a drawer.
The bony comes from the process of a long-necked, plant-eating dinosaur called a titanosaur. Scientists haven't yet identified the taxon it belongs to.
It was discovered successful 1985 during an expedition to Antarctica's James Ross Island and collected by geologist Mike Thomson. Working with the British Antarctic Survey, Thomson was mapping the area's stone layers and collected marine reptile fossils to assistance with aboriginal dating efforts. He recorded the find arsenic a ample reptile.
Decades later, paleontologist Mark Evans spotted the bony successful the British Antarctic Survey's collections and wondered whether it mightiness beryllium a dinosaur.
"It's lone erstwhile you commencement reasoning 'what's successful this drawer,' that sometimes you travel crossed thing and you think, 'Ah, this looks interesting,'" Evans told BBC News.
He and different researchers analyzed the signifier of the bony and compared it to different much implicit dinosaur remains, confirming their discovery. The findings were published connected Monday successful the diary Acta Palaeontologica Polonica.
Dinosaur fossils are uncommon to find successful Antarctica due to the fact that of the unforgiving crystal caps. But millions of years ago, erstwhile this dinosaur lived, the portion was populated by lush forests — a "rather antithetic and overmuch much hospitable spot than we deliberation of today," said survey co-author Paul Barrett with the Natural History Museum successful London.
"This find represents lone the 2nd sauropod assemblage fossil known from Antarctica, though it was the archetypal dinosaur bony to beryllium collected from the continent," the study's authors wrote.

At astir 23 feet long, the dinosaur was tiny for its radical and whitethorn person been young erstwhile it died. Scientists don't cognize however the carnal met its end, but they deliberation its assemblage floated distant from the seashore and sank to the oversea floor, becoming fossilized successful marine rock.
More than 100 taxon of titanosaur person present been identified astir the world, according to the BBC. All of them are four-legged works eaters, with precise agelong necks that helped them scope up into trees and agelong counter-balancing tails. The biggest titanosaurs were much than 115 feet agelong and weighed astir 60 tons.
Technology has travel a agelong mode since the dinosaur process bony was archetypal found, allowing researchers to adjacent wrong bones and summation adjacent much elaborate accusation astir past creatures. Thomson died successful 2020 earlier the fossil was identified arsenic belonging to a dinosaur.
"If helium were inactive with us, helium would beryllium delighted to cognize what this was," Evans, a survey co-author, said.
