Fascinating
discoveries were recently made by paleontologists
digging in two completely seperate locations . . . one
in the Gobi Desert, and the other at Dinosaur Provincial
Park in Alberta, Canada. The finds consisted of
two fossilized heads of ornithomimid
dinosaurs,
and they resemble, strangely enough, the head of a duck.
One
found in 1995 and the other in 1999, these peculiar
reptiles, when living, probably looked something similar
to an ostrich, according to experts. They were theropod
dinosaurs, a group that also includes Tyrannosaurus Rex.
There
are strange coincidences, however, that lead one to
think that, perhaps, they are indeed just the heads of
ducks (or an extinct species). Made of keratin,
just like a duck, these fossils also possess inside the
mouth a sieve-like structure that would have been used
for filter-feeding, just as in ducks. Furthermore,
the actual bodies of the specimens were not found,
forcing one to guess as to how they really looked.
Regarding
the long-debated issue of whether birds evolved from
dinosaurs, these finds apparently don't lend any help.
Experts do not believe these dinosaurs were ancestors of
ducks, so the search still continues for "the
missing chain."
Duckbilled
dinosaurs aren't anything new. Other such
species', like the hadrosaurs, also possessed bills,
though were much larger than these recent fossil finds.
Simply put, a bill doesn't make a reptile a bird anymore
then it does a duckbilled platypus. A peculiar
mammal quite unlike any other in the animal kingdom, the
billed platypus is an inhabitant of Tasmania and
southern and eastern Australia.
Compare.
This is a vital key in paleontology . . . one which,
only too often, is seemingly ignored.
