New E. Wyoming Triceratops find (with associated nanotyrannus teeth)



(Written from memory so a detail or two may be off)

Today's (5/4) Casper Star Tribune (of Casper, Wyoming) carries news of a
triceratops find in eastern Wyoming.

The find is located on a ranch 40 miles north of Lusk. The ranch is run by
Arlene and Leonard Zerbst, who found the remains last October and have named
the triceratops "Kelsey" after their daughter.

The Zerbsts contacted the Black Hills Institute about the find. Institute
president Gary Larson states that Kelsey appears to be around 50% complete,
lacking the tail, front limbs, and hind feet (implying the hind limbs
are present). Larson says this would place this find in the top ten
triceratops remains, if not the top five, as most remains do not often
have substantial post cranial remains.

The age of the find is not yet established, but the marine deposits
below Kelsey are dated at 100,000 to 500,000 years before the end
of the Cretaceous.

As if this weren't enough, the Zerbsts say they've located another
triceratops, yet to be worked on, which they say they'll name after
their grandson Lane.

The fossil, once excavated, will sold.

Excavation is ongoing. 

The Tribune has a web site, www.trib.com, but a quick check this morning
(5/4) did not show a web version of the article. A shame, as there was
an accompanying color picture of the remains clearly showing the skull.

Another interesting find was the presence of 20 nanotyrannus teeth asscociated
with the remains. The article remarked that this was interesting because a
nanotyrannus only has 50 teeth to begin with and that 20 would represent a
significant percentage of a single individual. The implications are that
more than nonotyrannus could be represented at the site. Further, that the
triceratops was possible killed/scavenged by a nanotyrannus, or by more
than one.

Even more interesting was that one of the teeth was more simliar to an
adult tyrannosaurus rex, which, the article remarked, could have an
affect on the debate over whether or not the nano form is a separate
species or a juvenile rex.
