Field
Guide to the Dinosaurs of the WitmerLab
The Young Scholars OHIO program—in conjunction with the
OU
Office of the Vice President for Research,
Department of Environmental and Plant Biology, and
Sarah Wyatt, PhD—brought about 42 profoundly gifted students from
10 states across the country (California to Maine to
South Carolina) for a range of enrichment programs at
Ohio University. WitmerLab
hosted nine of these students, aged 10–15 and hailing
from six different states, on 29 September
2015 for a
workshop entitled "Fleshing out dinosaurs with the
Visible Interactive Dinosaur Project" wherein the students worked with the
80+
dinosaur skull casts in the lab and with WitmerLab staff and
students to learn how paleontologists "flesh out"
out the past. In addition to discovering the diversity
and drama of dinosaur evolution, the students created
this Field Guide to the Dinosaurs of the WitmerLab...although
you'll note that many of the Young Scholars chose
non-dinosaurs as their faves! A
more complete photo gallery to our dinosaur skull cast
collection can be found on our
WitmerLab Collection page. All photography by Joel

workshop.

Becca & T.
rex
M'Kinzy &
hummingbird
My favorite creature from
today were the saber-toothed cats. I think it’s
really unique how recent the skeletons are in
comparison to the others, though they are
extinct. I thought their teeth, specifically the
large front two that could work as scissors with
the other teeth, were very interesting. I also
observed the dental structures of other
creatures like T-Rex and alligator and learned
how much they replace their teeth and how their
teeth can show their evolutionary heritage and
such. The Ankylosaurus was a close
runner-up.
The T. rex is a dinosaur from the Late
Cretaceous era. It is extremely large. The T.
rex is a carnivore, with very sharp teeth
that are great for slicing pray. It is a mighty
dinosaur, who always dominates. New! [Becca also has
Triceratops as a favorite and wrote up the
following report.] This dinosaur is commonly
known as Triceratops, the full scientific
name being Triceratops horridus. They
lived in the late Cretaceous era, 65 million
years ago, in what is now North America. They
had three tremendous horns which may have had
covers over them, such as today's pronghorns do.
These horns might have been used to knock over
taller plants to feed on. They also had an
enormous frill made of bone on their necks. The
adults grew to be around 26 feet long, and about
ten feet tall. Triceratops had up to 800 teeth
which like sharks, allowed for broken or worn
teeth to be continually replaced. As herbivores,
they ate a variety of plants, from shrubs to
palms. Triceratops had a beak-like mouth which
was very good for plucking leaves off of trees
and bushes. They laid eggs instead of having
live young and the females may have watched over
the nests. It's not exactly clear how long their
lifespan was. Some speculate that they lived as
long as today's giant tortoises.
The red throated hummingbird skull was my
favorite to learn about. Even with the tiny
tongue sticking out. While it’s tiny it’s not
the smallest hummingbird. That title goes to the
Cuban bee hummingbird. The unusual figure-eight
it forms with its wings when it flies sets it
apart from all the other birds.
Paxton &
Velociraptor
Madison & hooded seal
Joyce & alligator embryo
Hello, my name is Paxton, and I just went to a
Dino lab. And I decided my favorite dino is…Velcociraptor
because those dinos played a major role in
Jurassic Park. And I learned that dinos have
cousins (which are birds). So I hope that you
liked this doc, and GOOD-BYE. :) :)

I chose the Hooded Seal as my favorite animal in
the lab because I just think it is really
interesting. I remember us learning that the
Hooded Seal can close their nasal septa to
create an air bag like formation. A big white
thing comes out of their heads that makes it
looks like an airbag just inflated in a car. I
also learned that they can close only one of
their nasal septa to create a red bag that comes
out of the nostril. Once again, this creates a
shape that looks like an airbag. The reason it
is red is because that is the area where the
blood in the nose is held. And that is what I
have learned about the Hooded Seal.
Animal: Cleared & Stained Crocodile [Alligator]
Embryo
Why I like it:
-It’s small for a crocodile
-It’s blue
-You’re able to see the bones
-It’s see-through
-It’s dead
Michael &
Oviraptor
Ryan
& Parasaurolophus
Kareena
&
pronghorn
My favorite creature in the lab is Oviraptor.
Oviraptor is Latin for “egg taker” it was named such
because it was found near a nest of eggs. Scientists of
the day believed that Oviraptor was attempting to
steal the egg. However, modern scientists believe that
the animal was trying to protect its eggs, not trying to
steal the eggs of another. Oviraptor has a horn
like growth on the front of the skull. Scientists
believe that this was not used defense, due to its
fragile nature. Many theorize that this horn was used
for decoration. Whether it was used for mating, status,
or vanity is unknown at this time.
Parasaurolophus is my favorite dinosaur
because of their nose and how it works. I also
like it because it is the most extreme dinosaur
in its group because of its snout. The snout
helps keep the temperature low in the body.
My favorite animals in the Witmer Lab are the
pronged-horn antelope, bison, and goat. I think that
these animals are really cool because they have horns in
many different shapes and sizes. Once these animals are
dead, you can slide the keratinous sheath off of the
horns and see the “horn core”. Some of these horns are
twisted or curved and it is really interesting how the
horns are similar to the horns of the Triceratops
and the “horn family” of dinosaurs.
