and in such unusual circumstances,
researcher
Victor Beccari worked up this 3D model of the tapejarid. "Although we
don't know what colour the crest could be, a safe bet would be something in
between red and brown," Beccari says, the find is amazing as the remains
belong to a tapejarid, a toothless pterosaur from the early Cretaceous period
known for its huge cranial crest composed partly of bone and partly of soft
tissue, skulls and partial skeletons of Brazilian tapejarids have turned up
before, but this fossil was found with more than 90% of its skeleton intact,
along with some soft tissue in place around the bones, "This fossil is
special because it is the most complete pterosaur from Brazil and it brings new
information about the anatomy and ecology of this animal," says Victor
Beccari, co-author of a study on the find published last Wednesday in the
open-access journal PLOS One, the reptile
originally comes from the Crato Formation in the Araripe basin, a fossil-rich
area in north-eastern Brazil that dates back to a time in the Cretaceous period
around 115 million years ago. The remains were found preserved in six perfectly
complementary yellowish limestone slabs that fit together by rectilinear cuts
to present a nearly complete picture of the creature. It had a wingspan of more
than 8 feet (2.5 meters) and stood 3.2 feet (1 meter) tall, with its head crest
accounting for an astounding 40% of its height, but how was it found? Brazilian
federal police found the tapejarid remains while investigating an illegal
fossil trade operation in 2013. They recovered 3,000 specimens kept in storage
units in the states of São Paulo, Minas Gerais and Rio de Janeiro and
transferred them to the Geosciences Institute of the University of São Paulo
for study. Since 1942, Brazilian law has categorized fossils as state property,
as they're considered part of the country's geological heritage and
forbidden from being sold commercially, so now hopefully the specimen will be available
for researchers to study and not locked away in a private collection, no news of
any arrest as of yet.
