Here be monsters
Remains of giant sea-going
reptiles found in High Arctic
NUNATSIAQ NEWS
If you think an angry walrus
looks mean, imagine an Arctic ocean that once teemed with sharp-toothed creatures
that resemble the Loch Ness monster.
Researchers from McGill
University have unearthed the fossilized remains of several such sea creatures
on Melville Island, the Toronto Star reported this Tuesday.
Its the first time
some of these now-extinct creatures have been found that far North, the fossil-hunters
say, and in some cases, the first evidence some of these now-extinct creatures
lived on the North American continent.
One is the ichthyosaur,
a giant ocean-dwelling reptile that resembled a dolphin, with a broad body,
four flippers and a tail, matched with a head holding giant, bulging eyes and
a mouth full of sharp teeth.
The big eyes helped the
creature hunt prey during the night, scientists believe. It mostly fed on large,
prehistoric squid, fish and mollusks.
The specimen on Melville
Island includes pieces of the animals skull, backbone and flippers. These
fossils suggest the Arctic ichthyosaur was three to four metres long
far smaller than other specimens of the species, which was believed to reach
15 metres in length.
The fossils were found
among rocks about 120 million years old, dating back to the early Cretaceous
period.
Ichthyosaur remains have
been found around Asia, North America and Europe. Their appearance in the Arctic
could reveal a polar migration route of the creatures, according to Hans Larrson,
a McGill professor and a Canada Research Chair in vertabrate paleontology, who
is leading the research group.
The fossil-hunters also
discovered the remains of plesiosaurs another water-dwelling reptile
with a broad body and a long, snake-like neck.
These creatures are widely
believed to have died off 65 million years ago although some swear theyve
seen similar creatures in lakes such as Scotlands Loch Ness, and British
Columbias Lake Okanagan.
The plesiosaurs flippers
allowed the animal to deftly move about the water, while its long neck would
allow it to snap up unsuspecting fish.
Other finds include what
appears to be the remains of a Thalattosuchian, the modern crociles distant
relative, which has never been found before in North America.
The fossils will be studied
in detail when they are brought south. Until then, they sit in buckets, awaiting
transfer from the researchers field camp to Resolute.
