Jurassic Croc Found With Fish Like Tail
An ancient sea-going crocodile has surfaced from the rocks of Crook County
in eastern Oregon. Really.
It's discovery by the North American Research Group (NARG), whose members
were digging for Jurassic-age mollusks known as ammonites, is another
confirmation that the Blue Mountains consist of rocks that traveled from
somewhere in the Far East, says retired University of Oregon geologist
William Orr, who was called in to examine the find for the state.
The remains - about 50 percent of a 6- to 8-foot reptile, including long,
needlepoint teeth - were found imbedded in Jurassic rock on private
property in the Snowshoe Formation of the Izee Terrane south of Dayville,
"This taxon was a crocodile-like creature but had a fish tail," said Orr,
a NARG adviser and director of the Thomas Condon State Museum of Fossils
at the University of Oregon.
The remains of the crocodile, believed to be from the species
Thalattosuchia and member of the Metriorhynchids group, now belong to the
state, Orr said.
