Some questions

["Françoise Forel" <forelf@www.internet19.fr>]

Hello!

I had some problems with my computer so I am quite late.

For Tom Holtz:
Don't panic! I don't know any "Felice Landry"!

For Fred Bervoets:
I don't know a lot about the New Mexico shanshanosaurine. But the
Shanshanosaurinae is a real subfamily in the family Tyrannosauridae. This
group also contents _Stygivenator_ and _Alectrosaurus_. By the way, my name
is Félix Landry.

OK! I have some questions.

1) Jonathon Woolf speak of a new baby bird from Spain. I am very interested
by this animal because I have recently read an article by Peter Wellnhofer
called _Archaeopteryx_ in the book _Les Fossiles, Témoins de l'Evolution_.
This article speak of a lower cretaceous bird from Spain who loks like
modern birds. Wellnhofer say that this bird is as yet unnamed. But the
article is from 1991! Is these two animals the same?

2) Are _Unenlagia_ and _Protarchaeopteryx_ closely related?

3) Is _Unenlagia_ closely related to Alvarezsaurids?

4) What is the difference between a Mosasaur and a Pliosaur?

5) What was _Quetzalcoatlus_' size? I have read that we know the skull of
this giant Pterosaur. Is it correct?

6) Can you give me some mensurations (skull lenght, for exemple) for
_Tyrannosaurus_, _Giganotosaurus_, _Carcharodontosaurus_ and _Allosaurus_.

7) Was _Utahraptor_ as agile as _Deinonychus_ or _Veloiraptor_? Is 7 meters
the maximum size for a Dromaeosaurid?

Thanks in advence.
