  Troodon - Wikipedia, the free encyclopedia
Troodon formosus was a relatively small, bird-like dinosaur from the late Cretaceous Period (68–65 MYA).
Troodon (pronounced "Tro-odon") is Greek for "wounding tooth", and refers to the dinosaur's sharp teeth with serrated edges.
Troodon was first named Troödon (with a diaeresis) by Joseph Leidy in 1856, which was officially emended to its current status by Sauvage in 1876 — though both versions persist in common usage.

Troodon is a small meat eating dinosaur that is rare in more southern places like Alberta, Montana, and Texas.
Troodon's large eyes may have allowed it to be active at dawn and dusk, which would have allowed it to avoid direct competition for food with meat-eaters active during the day.
One of the striking aspects of the modern arctic is the angle of the sunlight and the length of the day, commonly, though mistakenly referred to as six months of daylight and six months of night.

Troodon was probably the smartest of the dinosaurs, with a relatively large brain for its body size.
Later, more complete skeletons were found, and it was discovered that Troodon had different types of teeth in different parts of its jaw, much as humans do.
Troodon was a lightly built dinosaur with a head sort of like a bird, and eyes that faced forward, like those of other hunters.

 Troodontidae
Even though dromaeosaur and troodontids are outwardly similar, scientists are not certain yet that they are closely related, but are confident that troodontids lie within the clade Maniraptora.
Troodontids are best exemplified by the genera Saurornithoides (from western Mongolia), Troodon (from North America), and Sinornithoides.
They were small (about the size of a small adult human), with long and slender hind limbs useful for rapid locomotion, and a long skull filled with distinctive recurved and saw-edged teeth (see the picture of two troodontid teeth from the UCMP collections).

Troodon may have hunted down small mammals such as Zalambdalestes, another fast inhabitant of the Mesozoic Era.
A pointed saw-edged tooth was named Troodon in 1856, and in the 1920s more discoveries seemed to show that it was the same as the bonehead Stegoceras.
So, after a complex history, in which Troodon has been classified as a lizard, a megalosaurid, a pachycephalosaur, and a hipsilophodontid, it turns out to be a saurornithoidid deinonychosaur-a lightly-built meat-eater that presumably had large slashing claws on it's second toes.

It's clear that some of the dinosaurs were getting smarter at the time the asteroid hit the Yucatan and handed the gauntlet to the mammals (fortunately for us).
Had the dinosaurs survived, argued Russell, and a species like Troodon grown smarter, it would eventually have needed to stand upright to balance its heavy head.

 Troodon Nests from Montana   (Site not responding. Last check: 2007-09-07)
Even more importantly, a recently discovered nest included partial remains of an adult Troodon that may have been brooding the eggs, much in the manner of the meat-eating dinosaur Oviraptor, whose nest sites have been found in Mongolia with complete skeletons of adults preserved while resting on clutches of twenty or more eggs.
Troodon produced two large eggs at a time, perhaps daily or at longer intervals over a period of weeks, and used and soil and direct body contact to incubate the clutch in an open nest -- there is no evidence of accumulated plant material at the known nest sites.
Coelurosaurs such as Troodon apparently resembled crocodiles in having two functional ovaries and oviducts (modern birds only use one).

The ultimate taxonomic survivor, Troodon started scientific life as a lizard species based on distinctive teeth, then was reclassified as a pachycephalosaurian, first as a synonym of Stegoceras, then as a dubious tooth taxon.
For a short period of time ending in the early 1980s, it was thought to be a carnivorous hypsilophodont (ironically, eggs once attributed to the hypsilophodont Orodromeus were recently thought to belong to Troodon, but new nests show they could not belong to it, but instead pertain to a currently-unknown theropod.
Later, a partial jaw was found containing Troodon teeth, and it was found to be the same (or maybe not!-stay tuned for future developments) animal as a "saurornithoidid" named Stenonychosaurus inequalis Sternberg, 1932.

Real Troodon dinosaurs looked something like big birds, but they were no chickens when it came to hunting prey, says dinosaur expert Michael Brett-Surman of the Smithsonian's National Museum of Natural History in Washington, D.C. Troodon dinosaurs would literally run down and rip apart their prey, usually small mammals or lizards, he says.
Troodon dinosaurs had a brain that scientists considered massive for the time, Lessem says.
A bigger brain probably allowed Troodon dinosaurs to hunt in packs, a relatively complex task that allowed them to attack larger animals, he says.

The trace comes from the Campanian, Late Cretaceous Two Medicine Formation of Montana, and consists of a bowl-shaped depression with an internal area of similar to 1m(2) surrounded by a distinct rim.
Clutch and nest size, shape, and symmetry and low organic carbon of the overlying mudstone suggests brooding rather than incubation with vegetative cover, although the latter cannot be ruled out.
Reproductive traits indicated by MOR 963 show that Troodon possessed plesiomorphies shared with crocodilians (some burial of eggs and lack of egg rotation), apomorphies shared with birds (open nests, exposed eggs, and incubation by a brooding adult), but also at least one unusual feature (steeply-inclined eggs) not found in either extant archosaur group.

That scene played out for the first time this past spring, when Troody—a 10-pound, two-legged robotic replica of a Troodon dinosaur from the Cretaceous period—took her maiden stroll through Peter Dilworth's lab.
He chose to model a Troodon for its small size and big brain: "The ratio of its brain size to its body weight makes it the brainiest of the dinosaurs," Dilworth says, "so I thought that was kind of interesting."
His objective was straightforward: "It was for the robot to stand up from a sitting position, to walk and possibly run, go back to walking and stop and then sit down and be stable, and not fall over in any phase," Dilworth explains.
