A police raid in South america has saved our scientific understanding of the incredibly well-preserved flying lizard that sported an unbelievably large mind crest.
Law enforcement have been investigating illegal fossil trade, as well as in 2013 found the pterosaur Tupandactylus navigans fossil amongst 3,000 other examples.
College of São Paulo paleontologist Victor Beccari and colleagues recognized they’d probably the most complete fossil of Tapejaridae (several crested pterosaurs) after piecing together the two-meter limestone slab that were sawed into six pieces to really make it simpler to cover.
CT scans helped reveal the astonishing detail from the animal’s unwieldy mind ornament – nearly half from the animal’s total height – imprinted within the stone, that the scientific study has just described inside a new paper.

Pterosaurs are relatively rare within the fossil record simply because they have fragile, thinly walled hollow bones that permit them to remain light for flight – formerly only fragments of tapejarid heads have been retrieved.
The lack of lake-floor dwelling creatures in which the fossil was hidden, in what’s the Crato Formation, suggests insufficient oxygen led to the outstanding upkeep of the fossil’s soft crest and beak tissues.
T. navigans were built with a strange crest jangling lower from the lower jaw too, as are visible in the stunning paleoart the recently revealed fossil is inspiring on Twitter.

“This pterosaur was over 2.5 meters (8.2 ft) in wingspan and it was 1 meter (3.3 ft) tall (40 % of the is taken into account through the mind crest),” Beccari told CNN. “With your a tall mind crest along with a relatively lengthy neck, this animal might have been limited to short-distance flights.”
Around 115 million years back, these ancient lizards might have used remarkable ability to fly to leave predators through the skies over what’s now northern South america, they explains. Their flight was based on a bone known as the notarium.
This bone is really a fusion from the first chest vertebrae that increases potential to deal with the bending and torsion stresses brought on by flapping wings the existence of the notarium confirms the pterosaur was indeed able to powered flight.

Evaluating the fossil to previous finds, they suspects some variations may be because of sexual dimorphism (where people of the identical species appear different based on sex) as opposed to the information on two distinct species as was thought so far.
This, however, needs further analysis to verify.
“Pterosaurs were already mind-blowing before, however this new specimen, using its huge, awkward crest and lengthy neck, is mind-boggling because – kind of like [flashy] peacock tails – they’d make him a beautiful mate, but a simple target for predators along with a poor flyer,” Beccari told New Researcher.
“Such as the peacock, it most likely spent it is time eating fruit off the floor or having its lengthy neck to seize food from greater shrubbery.”
Oh, my word, pterosaurs. What even _are_ you?

The illegal export of insightful fossils such as this one is a big problem for South america.
Fortunately, police thought it was prior to the fossil disappeared into the field of private collectors, to ensure that scientists could correctly examine it and share this ancient marvel around all.
The fossil was described in PLOS One.
