>Therezinosaurs are related to ornithomimosaurs,right(?)
Therizinosaur, not therezinosaur.
No, the vast majority of recent cladistic studies have them as cousins of the Oviraptorosauria. Ornithomimosaurs aren't even maniraptors (which therizinosaurs definately are) - although admittedly they were considered as possible therizinosaur relatives back in the 90s.
>And segnosaurs are closely related to therezinosaurs(?)
Segnosaurs ARE therizinosaurs.
Way back in 1954, Russian palaeontologist Evgenii Aleksandrovich Maleev described *Therizinosaurus cheloniformis* from a few bits and pieces discovered in 1923 (including the enormous claws) and erected the "family" Therizinosauridae to accommodate it. Incidentally, he thought it was was a turtle (!!!).
Now fast forward to 1979: Mongolian palaeontologist Altangerel Perle describes *Segnosaurus galbinensis* and erects the Segnosauridae to accomodate it. Next year he pens *Erlikosaurus andrewsi* and in 1983, with comrade Rinchen Barsbold, bags *Enigmosaurus mongoliensis*, both of which are also shoved in the Segnosauridae (the dinosaurs, not the palaeontologists) - although *Enigmosaurus* intially got its own family.
By the 1990s, it was becoming increasingly clear that *Therizinosaurus* and *Segnosaurus & friends* were effectively the same kind of critter - thanks mainly to the discovery of the decent skeleton of *Alxasaurus* in 1988 - and by the mid-90s, the Segnosauridae had been sunk into the Therizinosauridae.
> or if you can be nice, give me a whole list of segnosaurs, therezinosaurs, whatever.
Up to date complete lists of the Therizinosauria are to found at -
http://personal2.stthomas.edu/jstweet/therizinosauria.htm http://www.dinod ata.net/Dd/Namelist/CLASSIF/Therizinosauroidea.htm
Notethat there are a couple more possible bits of therizinosaur-material awaiting a full description.
>I'm trying to "expand my knowledge" on the Therezinosaurs,segnosaurs, since I really don't know to much about it.
Well...if you're after specific data, I have pdf descriptive papers for Beipiaosaurus & Falcarius plus hard copies for Eshanosaurus, Alxasaurus, Erlianosaurus & Nothronychus.

Ack - I'm afraid John Long has seduced me over to the dark side - next month I defect to Museum Victoria, studying basal actinopterygian fishies under him and Gavin Young (ANU). I get a whole range of perks including an ARC salary, free IMAX entry, my own Darth title and a spiffy red lightsaber. In case you didn't already know, Tiki buggered off thataway last month (applied for job at Scienceworks).
It will be a considerable step up in the world... I thought assembling WA Museum's Diprotodon was backbreaking, can't wait to kill myself on the Amargasaurus skeleton thats on the way to Melbourne!
Plus it will be nice being within driving distance from Koonawarra, Dinosaur Cove, Strzelecki etc...

What does pdf papers mean? Does that mean you have them on your computer and can email them to me? Sorry, I have no understandings of these things. |

Yes, a .pdf file is on the computer and can be read with Adobe Acrobat (available for free from numerous websites) or similar software.
A hardcopy means I either have the original journal or a photocopy of it.
