Fossils show flying reptiles ate squid and fish
Prehistoric flying reptiles lived on a diet of small fish and
squid, the latest scientific research has shown.
Researcher Dr Roy Smith said stomach contents
discovered in fossils were the "smoking gun" evidence for
the diets.
The findings were made by scientists from the University
of Portsmouth and the Staatliches Museum fur
Naturkunde Stuttgart in Germany and published in the
Journal of Vertebrate Paleontology.
Pterosaurs lived 182 million years ago and had
wingspans of up to 12m (39ft).
The team analysed the fossilised stomach contents of
two pterosaur species, dorygnathus and
campylognathoides.
They lived during the early Jurassic period, and were
found in modern-day south-west Germany.
They found that dorygnathus ate small fish for its last
meal while campylognathoides ate prehistoric squid.
Dr Smith, from Portsmouth University's School of
Environment and Life Sciences, said: "It is incredibly rare
to find 180 million-year-old pterosaurs preserved with
their stomach contents, and provides 'smoking gun'
evidence for pterosaur diets.
"The discovery offers a unique and fascinating glimpse
into how these ancient creatures lived, what they ate, and
the ecosystems they thrived in millions of years ago."
Dr Samuel Cooper, also from the University of
Portsmouth, said the stomach contents told scientists
"how the animals interacted with each other".
He added: "For me, this evidence of squid remains in the
stomach of campylognathoides is therefore particularly
exciting.
"Until now, we tended to assume that it fed on fish,
similar to dorygnathus, in which we found small fish
bones as stomach contents.
"The fact that these two pterosaur species ate different
prey shows that they were likely specialised for different
diets.
"This allowed dorygnathus and campylognathoides to
coexist in the same habitat without much competition for
food between the two species."
