How fast do you suppose raptors run, in comparison to
ornithomimids?

ESSAY
The only North American sauropod from the Late Cretaceous."
Aha! There's some stuff off the Dinosauricon - that should help.
Sauropod evolution: The Vulcanodontidae and the Indian Barapasauridae where
the first true sauropod families to evolve, in the early jurassic.
By the late jurassic they had evolved into six main groups, the Diplodocidae,
Dicraeosauridae, Euheloponidae, Cetiosauridae, Brachiosauridae and
Camarasauridae.
But by the cretacious, as plants started overtaking dinosaurs in the
evolutionary arms race, many herbivores where replaced by more adapted
animals, better suited to cope with plants that fight back.
This is quite a simple explanation, this site probably contains a lot of more
detailed information on sauropods.

Tetrapoda
Sauropsida
Archosauromorpha
Ornithodira
Dinosauria
Sauropodomorpha
Sauropoda
Macronaria
Titanosauria
LENGTH: 21 m MASS: 30 tonnes
Maastrichtian

Alamosaurus is the last ever known sauropod dinosaur - being from the
maastrichtian, Alamosaurus probably died in the great K-T extinction along
with T - Rex and other late cretacious dinosaurs.
So most of the above groups died off. But the sauropods wheren't over yet: The
Titanosauridae where a large group mainly present in South America, and there
is another group which is quite badly known, the Opisthcoelocaudidae.

"Does anyone have info on Alamosaurus"
Jeez, I am so glad that YOU don't think I'm evil Gianna.
Over the months I haven't been presenting myself so well I don't think...
Alamosaurus - I'll do some surfing, but shorthand I know the following:
Alamosaurus, named by Gilmore in 1922, late cretacious titanosaurid sauropod,
most titanosaurids, including I think Alamosaurus, had dermal oscicles, plates
and knobs of bone embedded in their skin as protection, and Alamosaurs had a
pair of little horns above each eye if I am not mistaken. About 21m long I
think, about Apatosaur size.

"BACK TO DINOSAURS.
How fast do you suppose Gallimimus ran?"
Well, I surfed a little bit and the general trend seems to be about 56km/h,
(that's 35mp/h) and I would be inclined to agree with that. That's racehorse
speed, by the way. Gallimimus had lots of big muscles around it's femur, and
the tibialis anterior muscle which bends your lower leg back towards the femur
seems to have been very powerful. And the metatarsals have been greatly
strengthened to endure big forces.
Does anyone have info on Alamosaurus "How fast do you suppose Gallimimus ran?" "So, I'm not going to ask you."
Oh; sorry. Tim asked me, though, before you posted. BACK TO DINOSAURS.
How fast do you suppose Gallimimus ran? Hi everyone!
I'm sorry I couldn- didn't, I mean, reply to all those posts, just I've bought
"Return to Castle Wolfenstein" on friday, and I've been solidly playing ever
since.
I told you I'm a harcore gamer!
And it's 9:04 now in England, and it's tuesday tommorow so I can't post now,
either! I'll give you some of my political views later. "Yes .sometimes if there is a sub-species they do have
a third part to there latin name."
Yes, like "-Equus-equus-caballus" and "-Equus-equus-prezwalskii" "Interesting. I have a question. If there are
different subspecies of a particular species, do they have three parts to their
latin name? A genus, a species, and a third part, for that particular subspecies?
I'm afraid no animals with three parts to their latin name spring to mind right
now, but I've certainly seen many animals with that."
Yes .sometimes if there is a sub-species they do have a third part to there latin
name.

Well, since by studying its footprints most people have come up with a top
speed that would be slightly slower than that of an Ostritch for
Dromiceiomimus, I'd assume that Gallimius would be slightly slpwer, since it's
larger and heavier. But then again, it would have a longer stride than it's
smaller relative, and like Ostritches and Emus, Ornithomimisaurs were probably
"striding walkers" who's speed depended partly on the great length of their
stride. But it's generally excepted that Dromiceiomimus was one of the
fastest, if not the fastest dinosaur. So I would say somwhere in beetween
30-45 as a maximus speed for this dinosaur.
