1 - General
Saurischian
True-False
Saurischians are divided into 2
definite clades: Sauropodomorpha &
Theropoda (although it is not
clear what to do with Segnosauria).
Ankylosaurs, Ceratopsians, Ornithopods, Pachycephalosaurs and Theropods all had their maximum diversity during the Late Cretaceous.

Theropods
True-False
All theropods were obligatory
bipeds.
Interlocking zygopophyses in the back half of their
tails resulted in
Ceratosaurs having their stiff
tails.
Ceratosaurs are noted for their stiff tails, which result
from interlocking
zygopophyses in the back half of their
tails.
Coelurosaurs are a clade of birdlike forms that share
a number of traits,
especially a semilunate carpal bone.
A number
of traits, especially a semilunate carpal bone, are shared by
Coelurosaurs,
a clade of birdlike forms.
Theropods had short femora compared to the rest of the hindlimb, indicating that they were generally fast runners.
Only dromeosaurids had
sickle-shaped claws on their second toes.
Sickle-shaped claws on
their second toes are possessed only by dromeosaurids.
No group of non-avian theropods lost many or all of their teeth.
Small theropods probably lived and hunted in packs.
Some theropods exhibit sexual dimorphism, with the larger form thought to be the female.

Birds
True-False
Archaeopteryx has only been found
in the late Jurassic Solnhofern
Limestone of Bavaria.
Birds
evolved from dinosaurs during the Jurassic Period.
Birds evolved
from dinosaurs during the Mesozoic Era.
Mesozoic birds differ from modern birds because they had teeth & long tails.
Whether or not coelurosaurs had clavicles has no bearing on the dinosaur - bird discussion.
A characteristic
of theropods that made it easier for birds to develop
flight was
hollow bones.
Hollow bones are a characteristic of theropods that
made it easier for birds
to develop flight.
No dinosaurs had
feathers.
Feathers were possessed by no dinosaur.
That
theropods & birds are bipedal supports the arboreal, not
the
cursorial, hypothesis for the development of bird
flight.
Support for the arboreal, not the cursorial, hypothesis
for the development
of bird flight comes from the fact that theropods
& birds are bipedal.
Mononykus is from the Gobi and has a weird short, stout carpometacarpus.
