Evidence of Huge Ancient Crocodile Found

WASHINGTON - In the era when dinosaurs ruled the Jurassic earth, a 13-foot
oceanic crocodile with a short snout and a mouthful of deadly teeth hunted
large creatures in the sea, scientists reported Thursday.
Nicknamed "Godzilla" by its discoverers, the new find was much different
from other marine crocodiles, which had long snouts with many small teeth.
The discovery of the creature, given the scientific name Dakosaurus
andiniensis, was reported Thursday in ScienceExpress, the online edition of
the journal Science.
"This animal was one of the latest members of its family and certainly the
most bizarre of all marine crocs," said Diego Pol of Ohio State University,
one of the authors of the report.
Lead author Zulma Gasparini of Argentina's National University of La Plata
said the "animal's anatomy is really a contrast with that of the other sea
crocs that developed during the Jurassic," about 135 million years ago.
The long narrow snout and small teeth of most crocs indicate feeding on
small prey, Pol said, while Dakosaurus' large serrated teeth indicate a
carnivore that would have hunted large prey.
"This was a top predator that probably was 13 feet long and swam around
using its jagged teeth to bite and cut its prey, like dinosaurs and other
predatory reptiles did," Pol said.
Instead of legs, Dakosaurus had four paddle-like limbs and a vertically
oriented, fishlike tail. Dakosaurus would have regularly surfaced to gasp
oxygen and then could dive into the ocean.
"We are calling him the 'chico malo' ? 'bad boy'" of the ocean, said
Gasparini.
While Dakosaurus had been known from a few bone fragments previously, the
new detail comes from a complete skull found in Argentina in 1996 and
studied by Pol, Gasparini and colleagues. The area where it was found had
been a deep tropical bay during the Jurassic period.
The world's relatively shallow seas between 230 million and 65 million years
ago contained several large animals, such as the plesiosaur with a 20-foot
neck and the giant ichthyosaurs that could be 75-feet long.
The research was funded by Argentina's National Council of Scientific and
Technical Research and the National Geographic Society. The discovery will
also be featured in the December issue of National Geographic Magazine.
