A dinosaur fossil that was beforehand considered a terrifying ‘raptor-like’ carnivore is definitely a timid vegetarian that lived 220 million years in the past, a brand new evaluation has revealed.
The fossil footprints have been present in an Australia mine round 50 years in the past, and have been thought to belong to an enormous theropod predator.
Nonetheless, a brand new evaluation by researchers from the College of Queensland has confirmed that the prints have been really left by a Prosauropod – a small and timid vegetarian.
Hendrik Klein, co-author of the examine, mentioned: ‘That is nonetheless a major discovery even when it is not a scary Triassic carnivore.
‘That is the earliest proof we’ve got for such a dinosaur in Australia, marking a 50-million-year hole earlier than the primary quadrupedal sauropod fossils recognized.’

The fossils have been found greater than 50 years in the past round 200 metres deep underground at an coal mine simply west of Brisbane.
Dr Anthony Romilio, who led the examine, mentioned: ‘It will need to have been fairly a sight for the primary miners within the Nineteen Sixties to see massive bird-like footprints jutting down from the ceiling.’
Researchers from the College of Queensland have now reanalysed the footprints, having suspected one thing was not fairly proper with the unique evaluation.

Dr Romilio defined: ‘For years it has been believed that these tracks have been made by an enormous theropod predator that was a part of the dinosaur household Eubrontes, with legs over two metres tail.
‘This concept brought on a sensation a long time in the past as a result of no different meat-eating dinosaur on the earth approached that dimension in the course of the Triassic interval.
‘Sadly, most earlier researchers couldn’t immediately entry the footprint specimen for his or her examine, as an alternative counting on previous drawings and pictures that lacked element.’
The brand new evaluation signifies the tracks have been made by a dinosaur often called a Prosauropod – a vegetarian that was smaller, with legs about 1.4 metres tall and a physique size of six metres (artist’s impression)
Whereas the mine has lengthy been closed, geologists mapped the trackway and made plaster casts of the fossils in 1964, which the researchers used within the new evaluation.
‘We made a digital 3D mannequin of the dinosaur footprint that was emailed to staff members the world over to check,’ Mr Klein mentioned.
‘The extra we seemed on the footprint and toe impression shapes and proportions, the much less they resembled tracks made by predatory dinosaurs – this monster dinosaur was undoubtedly a a lot friendlier plant-eater.’
Somewhat than being left by a carnivorous raptor-like dinosaur, the brand new evaluation signifies the tracks have been made by a dinosaur often called a Prosauropod – a vegetarian that was smaller, with legs about 1.4 metres tall and a physique size of six metres.
KILLING OFF THE DINOSAURS: HOW A CITY-SIZED ASTEROID WIPED OUT 75 PER CENT OF ALL ANIMAL AND PLANT SPECIES
Round 66 million years in the past non-avian dinosaurs have been worn out and greater than half the world’s species have been obliterated.
This mass extinction paved the way in which for the rise of mammals and the looks of people.
The Chicxulub asteroid is usually cited as a possible explanation for the Cretaceous-Paleogene extinction occasion.
The asteroid slammed right into a shallow sea in what’s now the Gulf of Mexico.
The collision launched an enormous mud and soot cloud that triggered world local weather change, wiping out 75 per cent of all animal and plant species.
Researchers declare that the soot essential for such a worldwide disaster might solely have come from a direct affect on rocks in shallow water round Mexico, that are particularly wealthy in hydrocarbons.
Inside 10 hours of the affect, an enormous tsunami waved ripped by way of the Gulf coast, consultants imagine.

This brought on earthquakes and landslides in areas so far as Argentina.
Whereas investigating the occasion researchers discovered small particles of rock and different particles that was shot into the air when the asteroid crashed.
Known as spherules, these small particles coated the planet with a thick layer of soot.
Specialists clarify that dropping the sunshine from the solar brought on an entire collapse within the aquatic system.
It’s because the phytoplankton base of virtually all aquatic meals chains would have been eradicated.
It is believed that the greater than 180 million years of evolution that introduced the world to the Cretaceous level was destroyed in lower than the lifetime of a Tyrannosaurus rex, which is about 20 to 30 years.
