Confusion over classification of dinosaurs
Robert Townsend posted several questions on my message board, but I've
got no time to reply them:
Confusion over classification of dinosaurs.
Monday, 29-Nov-1999 15:09:48
1. World famous palaeontologist Robert T. Bakker recently discovered a
new 'miniature' version of Tyrannosaurus
Rex and named it Nannotyrannus, meaning 'little tyrant'. How does he
and other palaeontologists know this is a
completely new genus and species and NOT just a juvenile or
'half-grown' T. Rex?
2. Is the English dinosaur Baryonix Walkerii, with a head similar to
the giant Suchomimus Tenerensis, just a
Spinosaurid without a sail, or is it still classified as a
3. Is Yangchuanosaurus the Chinese eqivalent of the North American
Allosaurus or Ceratosaurus, I have conflicting
information on this?
4. Were there any known sauropods that survived right up until the end
of the cretaceous?
5. In the last century, Edward Drinker Cope discovered a meat eating
dinosaur which he named 'Laelaps'. It is now
known as Dryptosaurus, the 'wounding reptile'. It has two fingers on
each hand and looks for all the world like a
member of the Tyrannosaurid family. So why isn't it classified as
6. Why do there seem to have been no large ceratopsians on any other
continent besides North America?
I hope someone with some expert knowledge can answer my questions.
