<P> One of the most famous and popular <LINK content="dinosaurs"/>,
<NOMEN name="Allosaurus"/> is known primarily from the Morrison Formation.
It probably hunted <LINK content="stegosaurs"/>,
<LINK content="iguanodonts"/>, and perhaps gigantic
<LINK content="neosauropods"/> like <NOMEN name="Diplodocus"/> and
<NOMEN name="Camarasaurus"/>. Its main rival was
the slightly smaller <NOMEN name="Ceratosaurus"/>. </P>

<P> There is debate over the taxonomy of these species. Some feel they
should all be lumped into <NOMEN name="A. fragilis"/> while others would
split them into several genera (<NOMEN name="Creosaurus"/>,
<NOMEN name="Epanterias"/>, etc.) </P>

 <ESSAY>
<P> The name <NOMEN name="Altispinax dunkleri"/> was once used to indicate
remains of a theropod with high vertebral spines, similar to those of
<NOMEN name="Spinosaurus"/>. In fact, the type material for this species
is merely teeth, teeth which can not confidently be assigned to the same
animal as the skeletal remains. The bones were reassigned to a new
species of <NOMEN name="Acrocanthosaurus"/>, another high-spined theropod.
This species was called <NOMEN name="A. altispinax"/>. But further study
indicated that it could not confidently be said to belong to the genus
<NOMEN name="Acrocanthosaurus"/>. Hence, it was placed in a new genus and
is now known as <NOMEN name="Becklespinax altispinax"/>.
<NOMEN name="Altispinax dunkleri"/> is now a dubious species. </P>

<P> The origin of <LINK content="birds"/> is associated with this creature,
the "first bird" (nicknamed "Archie"). Although it resembled other small
<LINK content="theropods"/> so much that one skeleton was for years
mistakenly identified as <NOMEN name="Compsognathus"/>, it bore feathers
identical to those of <LINK content="modern flying birds"/>. When it was
first discovered in 1861, early evolutionists quickly recognized it as the
"missing link" between birds and more primitive <LINK content="reptiles"/>.
</P>
  
<P> In many ways, <NOMEN name="Archaeopteryx"/> was unlike modern birds.
Like non-<LINK content="avian"/> <LINK content="dinosaurs"/>, it had a bony
tail (short for a theropod, very long for a bird), teeth, and clawed fingers.
It also had a hyperextendable "switchblade" claw on each foot, like its
relatives the <LINK content="dromaeosaurids"/>. But it was a bird and
featured avian characteristics, like a reduced number of tail vertebrae and
unserrated teeth. </P>

<P> The fourth non-<LINK content="avian"/> discovered to have feathers or

as the other four (<NOMEN name="Sinosauropteryx"/>,
<NOMEN name="Protarchaeopteryx"/>, <NOMEN name="Caudipteryx"/>, and
most recently <NOMEN name="Sinornithosaurus"/>).
<NOMEN name="Beipiaosaurus"/>' integument seems somewhat similar to that
of <NOMEN name="Sinosauropteryx"/>, but longer -- 5 cm on the average and
up to 7 cm on the arms. The ends seem to have branching structures. </P>

<P> Apart from the integument, <NOMEN name="Beipiaosaurus"/>, a primitive

<LINK content="coelurosaurian"/> <LINK content="theropods"/>, not

sometimes thought. Unlike most other theropods, therizinosaurs have
four functional toes, like sauropodomorphs and some ornithischians.
But <NOMEN name="Beipiaosaurus"/>' feet, which have reduced inner toes,
show that the therizinosaur condition evolved from a three-toed ancestor.
</P>

<P> <NOMEN name="Carnotaurus"/> was an unusual <LINK content="theropod"/>.
The name refers to the small horns it bore above its eyes. The arms were
extremely small and underdeveloped, even more so than those of the <LINK

appeared to sprout almost directly from the elbows. Remains are very
complete, with skin impressions that show rows of large, non-bony,
semiconical scales along the right side of the body. </P>
  
<P> <NOMEN name="Carnotaurus"/> was featured in the book <U>The Lost

camouflage. Even if this is blatantly unscientific, it would've looked

<P> <NOMEN name="Coelophysis"/>, a very common little hunter of the Late
Triassic, came in two forms, "robust" and "gracile". These two forms, or
"morphs", probably represent the two genders. </P>
  
<P> There was a recent disagreement over the proper name for <NOMEN
name="Coelophysis"/>. The type specimen (that is, the specimen used to
define the genus) was rather fragmentary. Most of our knowledge of <NOMEN
name="Coelophysis"/> comes instead from dozens of very well-preserved
specimens found at a site called Ghost Ranch. Some scientists recently
argued that the Ghost Ranch <LINK content="dinosaurs"/> might not
necessarily be the same as the original <NOMEN name="Coelophysis"/>
specimen. They proposed a new name for the Ghost Ranch dinosaurs - <NOMEN
name="Rioarribasaurus"/>. But by this time the association of the name
<NOMEN name="Coelophysis"/> with the Ghost Ranch material had become
heavily entrenched in dinosaur terminology. The ICZN (International
Committee on Zoological Nomenclature) voted to redefine the type specimen
of <NOMEN name="Coelophysis"/> as one of the Ghost Ranch specimens. So the
name <NOMEN name="Rioarribasaurus"/> has been officially dropped. </P>
  
<P> The original type material, which may or may not belong to the same kind
of animal as the neotype, has been given its own (dubious) genus:
<NOMEN name="Eucoelophysis"/> ("true <NOMEN name="Coelophysis"/>"). </P>

<P> A <NOMEN name="Coelophysis"/> skull from the Carnegie Museum of
Natural History became the first dinosaur fossil to be taken into space on
January 22, 1998 when the Endeavor Space Shuttle took off for Mir Space
Station. </P>

These frills were probably ornamental in nature. </P>
  
<P> <NOMEN name="Dilophosaurus"/> was featured in the blockbuster movie
<U>Jurassic Park</U>. Considerable liberties were taken with the
restoration. Real <NOMEN name="Dilophosaurus"/> were much larger than their
Jurassic Park counterparts. There is no evidence that they had neck frills or poison
glands. In fact, <NOMEN name="Dilophosaurus"/> was the largest predator in
its environment and had no need to be poisonous. Furthermore, Jurassic Park's
dilophosaurs had jaws simplified beyond recognition (the cool kink was
utterly smoothed out). </P>

<P> Discovery of <NOMEN name="Hadrosaurus"/> back in 1858 showed that some
dinosaurs were bipedal, correcting erroneous restorations of

<P> This was the first <LINK content="dinosaur"/> to be scientifically
recognized. Along with <NOMEN name="Megalosaurus"/> and
<NOMEN name="Hylaeosaurus"/> it was one of the first three creatures to be
placed in <LINK content="Dinosauria"/>. </P>
  
<P> <NOMEN name="Iguanodon"/> was originally restored as a four-legged,
rhinoceros-like beast. Later the "nasal horn" turned out to be a thumb spike.
Its posture was changed to bipedal, since its hindlimbs were so much longer
than its forelimbs. Nowadays it, like other large
<LINK content="iguanodonts"/>, is thought to have been facultatively bipedal,
that is, primarily quadrupedal, but capable of moving on two legs as well. </P>
  
<P> <NOMEN name="Iguanodon"/> as shown here may be a paraphyletic genus, with
some species, such as <NOMEN name="I. bernissartensis"/>, closer to
<LINK content="hadrosauroids"/>. As with most old genera, there is some
taxonomic sorting to be done. The type species (<NOMEN name="I. anglicum"/>)
is based on very poor material. </P>

<P> <NOMEN name="I. hollingtonensis"/> and <NOMEN name="I. atherfieldensis"/>
were rather gracile and long-spined, while <NOMEN name="I. dawsoni"/> and
<NOMEN name="I. bernissartensis"/> were more robust and short-spined. </P>

<P> <NOMEN name="Oviraptor"/> had a crest on its head, grasping hands, and
an unusual penchant for being fossilized in interesting positions. The first
one was found near what was thought to be the nest of a
<NOMEN name="Protoceratops"/>, presumably intent on snatching an egg. This
gave it its name, which means "<LINK content="ceratopsian"/>-loving egg
raider". </P>

<P> In fact, analysis of the fetuses inside the eggs have since shown it to
be the <NOMEN name="Oviraptor"/>'s own nest. More recently, another oviraptorid
(possibly <NOMEN name="Oviraptor"/>) has been
found which died in a sandstorm while sitting on a nest of its own brood.
These two discoveries show that <NOMEN name="Oviraptor"/> probably cared
for its offspring,  as <LINK content="birds"/> and
<LINK content="crocodylians"/> do today. </P>
  
<P> <NOMEN name="Oviraptor"/> was featured in the book <U>Dinotopia</U>,
where it was renamed <NOMEN nolink="1" name="Ovinutrix"/> ("egg nurse"),
since that was its function in the book's utopian society of prehistoric
animals and humans. Strangely enough, the name given in the
fictional book has turned out to fit the animal better than its actual name.

  <NOMEN name="Sinornithosaurus"/> is the one most closely related to

  <LINK content="deinonychosaurs"/> (a.k.a. "'raptors") were

  <P><NOMEN name="Sinornithosaurus millenii"/> has been diagnosed as a

  <P>The authors of this species have interpreted it as evidence for a
  "Ground Up" model of flight evolution (see 
  <LINK content="Avialae"/>). However, it may instead lend credence to the 
  idea that deinonychosaurs, and perhaps other coelurosaurs, are secondarily
  flightless (like <LINK content="ratite"/> birds), since it has more flight

<P> <NOMEN name="Sinosauropteryx"/> was one of the most exciting paleontological

<P> <NOMEN name="Sinosauropteryx"/> is important for at

  the argument that <LINK content="birds"/> are descended from 
  <LINK content="dinosaurs"/>. Secondly, depending on its exact phylogenetic 
  position, it shows that at least some non-<LINK content="avian"/> 
  <LINK content="coelurosaurs"/> were feathered.
  <LINK content="Deinonychosaurs"/>, <LINK content="oviraptorosaurs"/>, and
  <LINK content="therizinosaurs"/> are closer to

  animals from all three of these groups were found 
  (<NOMEN name="Sinornithosaurus"/>, <NOMEN name="Caudipteryx"/>, and
  <NOMEN name="Beipiaosaurus"/>, respectively). It may also be that 
  <LINK content="ornitholestids"/>, <LINK content="coelurids"/>,
  <LINK content="ornithomimosaurs"/>, <LINK content="troodontids"/>, and even
  <LINK content="tyrannosauroids"/> were closer to birds than
  <NOMEN name="Sinosauropteryx"/> was, making them probably feathered 
  (or secondarily featherless) as well. </P>

<P>The gigantic <NOMEN name="Spinosaurus"/> has been estimated at up to
fifty feet long. It was possibly the longest <LINK content="theropod"/>,
but not the biggest, since it was more lightly built than the heavier
<NOMEN name="Tyrannosaurus"/> and <LINK
content="carcharodontousaurines"/>.</P>
  
  <P>As remarkable as its length was, even more interesting was the huge sail
  along the back, formed by long vertebral spines, up to six feet in height
  at places. The exact nature of this bizarre sail is not known. It may have
  been used for heat dissipation, like the ears of modern-day elephants.
  Or perhaps it was a sexual signal. Similar structures were present in
  the <LINK content="ornithopod"/> <NOMEN name="Ouranosaurus"/> and the
  <LINK content="sauropod"/> <NOMEN name="Rebbachisaurus"/>, two 
  <LINK content="dinosaurs"/> living at the same time and area as
  <NOMEN name="Spinosaurus"/>. Some primitive amphibians and proto-mammals
  such as <NOMEN nolink="1" name="Dimetrodon"/> and
  <NOMEN nolink="1" name="Edaphosaurus"/> also bore similar sails back in the
  Permian. Such parallelism across so many diverse groups is a strange
  phenomenon.</P>

 <ESSAY>
<P> <NOMEN name="Therizinosaurus"/> was named for remains from the southern Gobi Desert,
  which included huge claws measuring up to 28 inches (and that's without the
  horny sheath that covered them in life!) as well as seven-foot-long arms
  and some flattened ribs. They were originally thought to be remains of a
  giant <LINK content="turtle"/>-like creature (hence the specific name 
  <NOMEN name="T. cheloniformis"/>). </P>
  
<P>  More remains were found in Kazakhstan, Transbaykalia, and Inner Mongolia
  in the late 50's, including a partial forelimb, partial hindlimbs, and a
  tooth. The new discoveries showed that <NOMEN name="Therizinosaurus"/> was not a
  turtle at all, but a <LINK content="dinosaur"/>, probably a new kind of
  <LINK content="theropod"/>. (The ribs of the first specimen may belong to a
  <LINK content="sauropod"/>.) </P>
  
<P>  <NOMEN name="Therizinosaurus"/> was kept in its own group for a long time. 
  Only recently have scientists discovered its close relation to the bizarre
  segnosaurs (now known as <LINK content="therizinosaurs"/>). </P>
  
<P>  One of the most striking characteristics of <NOMEN name="Therizinosaurus"/>
  (apart from the myriad of striking characteristics it shares with other
  therizinosaurs) is the huge, blade-like claws on the hand. Other
  therizinosaurs had them, but none as insanely large
  as those of <NOMEN name="Therizinosaurus"/>. </P>
  
<P>  Many ideas have been postulated about these claws. It has been suggested
  that therizinosaurs used them to rip open giant termite nests, like
  anteaters and aardvarks. But the idea that an animal of
  <NOMEN name="Therizinosaurus"/>' size (over 30 feet long) could subsist on a 
  diet of insects seems rather unlikely.  </P>
  
<P>  Instead, the claws may be analogous to those of the
  extinct giant ground sloths and chalicotheres (relatives of horses).
  Members of both of these groups were quite large in size and bore huge,
  blade-like claws on their hands. They were both herbivorous, as
  therizinosaurs probably were. It has been suggested that they used their
  claws when browsing to bring foliage closer to their mouths. They would 
  also have come in handy as defensive weapons. </P>
  
<P>  The giant <LINK content="ornithomimosaur"/> <NOMEN name="Deinocheirus"/> is another mysterious
  theropod known mostly from gigantic arms. Strangely enough, it comes from
  the same time and place as <NOMEN name="Therizinosaurus"/>. </P>
  
<P>  Huge fossilized eggs found in Mongolia (13cm diameter, 45cm long) have been
  attributed to <NOMEN name="Therizinosaurus"/>, or possibly <NOMEN name="Tyrannosaurus"/>.

 <ESSAY>
<P> <NOMEN name="Tyrannosaurus rex"/>, possibly the most popular <LINK
content="dinosaur"/> ever, was for a long time the largest known
terrestrial predator. But new discoveries of <LINK
content="carcharodontosaurines"/> have recently ousted the "king of the
tyrant lizards" from its title. But there still remains the possibility
that an even larger <NOMEN name="T. rex"/> specimen may be found some day.
And it <U>was</U> the largest known predator of its time, at the end of
the Mesozoic Era.</P>

<P> The most complete <NOMEN name="Tyrannosaurus"/> skeleton, a female(?)
<NOMEN name="T. rex"/> (=<NOMEN name="T. stanwinstonorum"/>) nicknamed "Sue",
was recently sold for over $7 million by Sotheby's to corporate benefactors
on behalf of the Chicago Field Museum. </P>

<P header="Odd Remains"> Recently an enormous coprolite (fossilized piece of dung) from
Saskatchewan was referred to <NOMEN name="T. rex"/>. At 43cm in length and
2.4L in volume, this is the largest known coprolite from a carnivore. Tiny,
well-crushed bone fragments indicate that the meal was a small subadult
<LINK content="ornithischian"/>. </P>

<P> Eggs tentatively assigned to <NOMEN name="Therizinosaurus"/> may belong
to an Asian species of <NOMEN name="Tyrannosaurus"/>. </P>

<P header="Classification"> The various species included here in <NOMEN name="Tyrannosaurus"/> are
sometimes placed in other genera. <NOMEN name="T. efremovi"/> was originally
<NOMEN name="Tarbosaurus"/>, and sometimes <NOMEN name="Tyrannosaurus bataar"/> is also
included in that genus. Others put <NOMEN name="T. bataar"/> into its
own genus, <NOMEN name="Jenghizkhan"/>. Still others consider
<NOMEN name="T. efremovi"/> to be the subadult stage of
<NOMEN name="T. bataar"/>. </P>

<P> <NOMEN name="Tyrannosaurus novojilovi"/> and <NOMEN name="T. lancensis"/>
were thought by some to be pygmy <LINK content="tyrannosaurins"/>,
and were accorded their own genera (<NOMEN name="Maleevosaurus"/> and
<NOMEN name="Nanotyrannus"/>, respectively). But they seem instead to
be juveniles. <NOMEN name="T. novojilovi"/> likely belongs to
<NOMEN name="T. bataar"/> or <NOMEN name="T. efremovi"/>, and
<NOMEN name="T. lancensis"/> likely belongs to <NOMEN name="T. rex"/>.
<NOMEN name="T. megagracilis"/> also likely belongs to <NOMEN name="T. rex"/>,
representing the subadult stage. It is sometimes placed in
<NOMEN name="Dinotyrannus"/>. </P>

<P> <NOMEN name="T. luanchuanensis"/> and <NOMEN name="T. lanpingensis"/>,
both dubious tooth taxa, probably belong to either <NOMEN name="T. bataar"/>
or <NOMEN name="T. efremovi"/>. </P>
