Topic: Maniraptor


  
  Maniraptora - Encyclopedia.WorldSearch   (Site not responding. Last check: 2007-10-20)
It is a sister group to Arctometatarsalia, and contains the subgroups Deinonychosauria, Oviraptorosauria, Therizinosauria, in addition to Aves (birds).
Maniraptors are characterized by elongated arms and hands, as well as a semi-lunate carpal in the wrist.
Other basal maniraptor traits include the presence of a furcula, a distally shortened and stiffened tail, feathers, and an elongated, backwards-pointing pubis.

 Therizinosauria (As)
In the therezinosaurs, however, the divergence from the carnivore root stock is carried to extremes; they have abandoned all of the tendencies that their ancestors have held for over a hundred million years, and have become herbivores.
The hips of a therezinosaur are much wider then is normal for a maniraptor, and the pubis is swept backward in the manner of a bird or ornithischian dinosaur, to accommodate the large belly needed to digest plant matter.
The partial thawing of Earth's polar reaches has allowed orithscian herbivores, such as the formosicorns, the cenoceratopsians, and the viriosaurs to expand northward, chewing away at the therizinosaurs' strongholds.

Like all maniraptors, segnosaurs are bipedal, covered in feathers, and have hands bearing three fingers each, but there the resemblance with the maniraptoran root-stock stops (if one doesn't plunge deep into the details of the skeleton).
The hips of a segnosaur are much wider than is normal for a maniraptor, and the pubis is swept backward in the manner of a bird or ornithischian dinosaur, to make room the large belly needed to digest plant matter.
In Asia and the Americas, however, these strange, lumbering maniraptors dominate the large herbivore guilds only in the frigid places, be they high in altitude or in latitude.

 What is a Raptor?   (Site not responding. Last check: 2007-10-20)
Some use the word to refer to the Maniraptoriformes, others the Maniraptors, while one, Dr. Robert Bakker, apparently, uses the term to refer to ALL dinosaurs.
Technically, raptors are a specific group of birds, the birds of prey.
See the DML Cladogram on Dinosauria On-Line for the animals that belong to the Maniraptor clade (be sure to read the introduction so you can read the clades properly).

However, it is interesting to know that at least some of the larger maniraptors evidently ceased to grow feathers, as large warm-blooded animals typically have trouble getting rid of their body heat.
Surprisingly, it wasn't even a maniraptor, though many of the differences are subtle.
It would appear that this animal is one of the therizinosaurs - formerly called segnosaurs - a group of huge, bulky maniraptors which used all four toes for walking, and had huge claws on their hands.

 Matt Martyniuk: Therizinosaurus   (Site not responding. Last check: 2007-10-20)
Their share a number of features with such diverse groups as prosauropods, ornithishians, and theropods, and have been placed in all three groups as various times.
Recently, with the discovery of primitive segnosaurs like Beipiaosaurus and Alxasaurus, it's been proven that therizinosaurs are in fact maniraptor theropods (most closely related to the oviraptors - together they form the group Enigmosauria), though extremely derived ones.
One notably reversed feature is the functional first toe, usually a small dewclaw in other theropods, and the bizarre looking hip bone arrangement.

I was wondering how you got your birds to roll over but my husband wants to know how you them to type!
hi there, nice site, id love to see details on the maniraptor dinosaur and the bird by comparing their cells.
By what % does a maniraptor's DNA differ from a bird's, like a chimp and a human DNA match up 99%?

As a result, the term "raptor", as it applies to certain non-avian dinosaurs, will often have differing meanings.
Occasionally it will be used to refer to anything in the Maniraptor clade, which includes both the Dromaeosauridae and the Aves (birds), even though this usage has the strange effect of making both raptorial and non-raptorial birds "raptors."
Usually, though, the term will be used to refer to the Dromaeosauridae, a family of dinosaurs that does include

I still have yet to get any response from either Feduccia or Martin concerning the egg microstructure evidence (ornithoid only in maniraptors and early birds).
However, "Cal King" (that anonymous defender of Feduccia's ideas) posted the response given below.
