"I THINK THIS ONE CAME FROM SOUTH EAST ASIA"
China to be presice.

"WELL EVERYONE KNOWS THAT THE METATARSLAS ARE YOUR FOOT BONES"
Well, only well educated people do here.

"AND "ARCTOS" MEANS NORTH."
Actually, in "Arctometearsalia" the "Arcto" comes from the latin word "arctus" meaning compressed. That make sense, being the Arctometarsalian condition is the proximall pinch of the third metatarsal in beetween the second and fourth metatarsal.

"I THINK YOU MEANT TO SAY "ARCTOMETATARSALIAN PES.""
Nope, I didn't. The Arctometartarsalia as first defined by Holtz in 1994 was supposed to be the first dinosaur with the Arctometartarsalian condition, and all of its descendants which would in that case consist of the Bullatosauria(Troodontidae+Ornithomisauria), the Tyranosauridae, the Elmisauridae(a.k.a Caegnathidae), and Avimimus. But Holtz soon realized that an apomorphy based definition would be unstable because the condition was also found in Monokyus, Elmisaurs are more closely related to Oviraptorids then they are to the other Arctometartarsalian therepods, and Avimimus might be several different taxa. So he redifined Arctometartarsalia as a stem based taxon comprising of Ornithomimus and all therepods closer to it than to birds. Therefore the Arctometartarsalia consists primarily of the Bullatosauria and the Tyrannosauridae.(Yes, Tyrannosaurs are more closely related to Troodontids than Dromeosaurs are)

"Here is a trivia question.

Which one of these dinos were found in Africa?

A. Tescelosaurus <-- USA I THINK

B. Majungatholus <-- THIS ONE WAS FOUND IN MADAGASCAR, CLOSEST TO AFRICA THAN WHERE I THINK THE OTHERS WHERE FOUND.
C. Beipiaosaurus <-- I THINK THIS ONE CAME FROM SOUTH EAST ASIA.

Good Luck

I'll try and get people to come back to this forum: here's some trivia!
1. What is the definition of the Arctometartarsalia. WELL EVERYONE KNOWS THAT THE METATARSLAS ARE YOUR FOOT BONES, (WELL MAYBE NOT IN THIS COUNTRY, NO OFFENSE TO ANYONE,) AND "ARCTOS" MEANS NORTH. I THINK YOU MEANT TO SAY "ARCTOMETATARSALIAN PES." THE FOOT ABOVE THE METATARSALS. THE TARSALAS, BASICALLY. YOUR ANKLE. DOES IT INCLUDE THE CALCANEUM IN THIS CASE?
2. When did Cope establish the Archosauria. I WON'T TRY TO GUESS BECAUSE THE ODDS OF ME GETTING IT WRONG ARE QUITE HIGH.
Good luck."

Sorry.

"2) Tom; his day is 17th March."

My birthday is on the 17th of march but i turn 13 on the 17th march so i'm almost 13 not almost eleven.
from Tom G, age almost 13, ?, ?, ?; February 8, 2002


"2) Tom; his day is 17th March"
Isn't Tom twelve?

from Tim M., age ?, ?, ?, ?; February 8, 2002


"3 people?"

Yup.

1) You're 11 on 16th March.
2) Tom; his day is 17th March.
3) Joe Bob is apparently "almost 11" as well.

That's three.
from da masta, age 14, Birmingham, West Midlands, England, ?; February 7, 2002


"3 people?"
Yes,who's the third?

from Tim M., age ?, ?, ?, ?; February 7, 2002


3 people?
from gianna, age ?, ?, ?, ?; February 6, 2002


Ah, come on people! This forum's overgrown with spider webs!

"almost 11" That's three people who are almost eleven on this site then. So when's your day Joe Bob?

And don't expect new episodes of my story to come out really often because I rarely have the time to write more.

"Umm... Is anyone here?"

We're all here, I check out this forum every day in case someone decides to start a discussion! C'mon! WE NEED a topic! And don't look at me. I like arguing but I'm not good at coming up with... wait a sec!

I have this THEORY that some paleontologist or something else may have come up with ages ago but I've come up with it now so there!

I reckon that all ornithischian dinosaurs became from saurischians!

The first dinos where saurischian, herrerasurs, prosauropods, and the plant eating ornithischians (yes, I know that all orniths are herbivores!!!) developed from them! Their pubis just moved back to accomodate a larger gut used to digest tough plant food!
