Stenonychosaurus Dinosaur |
|
Stenonychosaurus (type genus S. inequalis) was named by C.M. Sternberg
in 1932, based on a foot, wreckage of a hand, and some caudal vertebrae
from the Late Cretaceous of Alberta. An extraordinary feature of these
remains was the distended claw on the second toe, now recognized as trait
of Deinonychosauria. Sternberg initially classified Stenonychosaurus as
a associate of the family Coeluridae within the theropod dinosaurs. Later,
Sternberg (1951) speculated that since Stenonychosaurus had a "very
peculiar pes" and Troodon "equally strange teeth", they
may be closely related. Unluckily, no comparable specimens were obtainable
at that time to test the idea. |

| A more whole skeleton of Stenonychosaurus was described by D.A. Russell
in 1969, which eventually shaped the scientific foundation for a famous
life-sized sculpture of Stenonychosaurus accompany by its fictional, human-like
descendant, the "dinosauroid". Stenonychosaurus became a well-known
theropod in the 1980s, when the feet and braincase were described in more
elements. It is sometimes listed as the "most intelligent" of
dinosaurs. P.J. Currie reviewing the known Troodontidae in 1987, reclassified
Stenonychosaurus inequalis as a junior synonym of Troodon formosus. This
synonomy has been extensively adopted by other paleontologists, and therefore
all of the specimens once called Stenonychosaurus are now referred to
as Troodon in the recent scientific text. Other taxa "lumped"
into Troodon are Pectinodon bakkeri and Polyodontosaurus grandis, which,
the length of with Stenonychosaurus inequalis may all be separate suitable
species, or belonging to one genus or species. |
