  Taxon Search : View Taxon Details
Hadrosauridae has been used variosuly to include two or more subfamilies (Lambeosaurinae, Hadrosaurinae) as well as well as several genera that might lie outside these, such as Telmatosaurus Weishampel et al.
Hadrosauridae, thus, was being handled as a trait-based taxon that incorporated new basal genera as they appeared; Weishampel et al.
In short, there is no advantage to placing Hadrosauridae among a graded series of stems rather than to recognize with a node-stem triplet a dichotomy that has long been a part of traditional taxonomy.

 Hadrosaurid - Wikipedia, the free encyclopedia
This has been hypothesized to have been a crucial factor in the success of this group in the Cretaceous, compared to the sauropods which were still largely dependent on gastroliths for grinding their food.
Sereno (2005) defines Hadrosauridae as the most inclusive possible group containing Saurolophus (a well-known hadrosaurine), Parasaurolophus (a well-known lambeosaurine), and Hadrosaurus (the type geus of the family, which ICZN rules state must be included, despite its status as a nomen dubium).
Probable hadrosaurids that cannot be assigned to either sub-family are listed under Hadrosauridae and preceded by a question mark.

Trachodon Prehistoric Animals Trachodon Pictures catalog extinct extinction endangered Trachodon is the name applied to one of the duckbilled DINOSAURS of the family Hadrosauridae (suborder Ornithopoda, order Ornithischia).
The name was proposed for a single fossil tooth, about 65 million years old, found in the Upper Cretaceous Judith River Formation of Montana--the first fossil remains of a duckbilled dinosaur to be found.
Anatosaurus, commonly believed to be identical to Trachodon, stood 5.5 m (18 ft) high on its hind legs, attained a total length of 12 m (40 ft), and weighed 6 tons or more.

The hadrosaurines lived during the Late Cretaceous Period and flourished in the lands of North America, Europe, and Asia.
Hadrosauridae (had-ruh-SAWR-ih-day) is a family of commonly referred to as "duck-billed dinosaurs." Bipedal, hadrosaurs could grow up to 40 feet (12 meters) long.
The dinosaurs of the Hadrosauridae family lived during the Late Cretaceous Period.

The caudal centra are anteriorly hexagonal, condition that has been interpreted as a synapomorphy of Hadrosauridae by many authors.
The fossils were found in sandy facies of littoral deposits, influenced by river flow and tides, related to the first Atlantic marine event for the Neuquén Basin.
From a paleogeographic standpoint, this new record of Hadrosauridae adds new evidence on the immigration of these dinosaurs from North America toward the end of the Cretaceous.

Without better specimens, it is impossible to know whether the chuanlong is an aberrant neohadrosaur, an aberrant ungulaped, or something else altogether.
Hadrosauridae consisted of two major groups, the flat-headed Hadrosaurinae and the hollow-crested Lambeosaurinae.
Their origins are unclear, but some evidence ties them to Telmatosaurus from the end-Cretaceous of Europe, one of the minor groups of Hadrosauridae.

 Palaeos Vertebrates 320.750 Ornithischia: Hadrosauroidea: Hadrosauridae
There are two current definitions of Hadrosauridae: (1) the last common ancestor of lambeosaurines, hadrosaurines, Telmatosaurus, Secernosaurus, and (one supposes) now Protohadros, and all of its descendants; and (2) only lambeosaurines plus hadrosaurines (sometimes called "Euhadrosauria").
Most writers, with the notable exception of Sereno, surrender to temptation and put a name to what is a essentially a grade or phenetic level between Hadrosauroidea and the Late Cretaceous lambeosaurines and hadrosaurines.
Notes: [1] As discussed in the essay, an alternate definition of Hadrosauridae takes in a number of more basal hadrosauroids which are neither hadrosaurines nor lambeosaurines.

The crests were gifts only in the Hadrosauridae family.
Hadrosauridae is divided in two sub-families: Lambeosaurinae and Hadrosaurinae.
In the first one, all the genera possessed crests, which were hollow and communicated with the respiratory ways.

 Hadrosaurs
When I lived in Montana, it seemed that everyone was familiar with the hadrosaur Maiasaura ("the good mother lizard"), discovered by local paleontologist Jack Horner of the Museum of the Rockies in Bozeman, Montana.
The Hadrosauridae, also known as the duck-billed dinosaurs, were members of the ornithischian ("bird-hipped") dinosaurs.
They were herbivorous (plant eating), and could probably switch easily from walking bipedally (on two legs), to walking quadrupedally (on all four legs) depending on whether they were feeding or running from predators.

Some divide into more than 2 sub-families, while others again split the group into 2 separate families, Hadrosauridae and Lambeosauridae.
Nowadays the term Hadrosauridae has been limited strictly to those dinosaurs belonging to either hadrosaurine or lambeosaurine sub-families, and a number of previous "Hadrosaurids" that cannot be confidently assigned to either sub-family are now grouped together as the Hadrosauroidea.
Hadrosaurines were a sub-family of hadrosaurs distinguished by having solid bumps on their heads, longer, narrower jaws than lambeosaurines, and relatively long, slim limbs.

Hadrosauridae: Hadrosaurids were long thought to have lived in water, another set of victims of the mindset that condemned sauropods as well to the watery regions.
As for the teeth, that is a patent lie.

 Palaeos Vertebrates 320.700 Ornithischia: Hadrosauroidea
[2] Norman (1990) places Probactrosaurus as the sister of Hadrosauridae, and Ouranosaurus as an iguanodontid.
Accordingly, the characters from [N90] actual characterize a different, unnamed group: Probactrosaurus + Hadrosauridae.
When I run his data set, Ouranosaurus comes out as a hadrosauroid, but, as Head notes, the synapomorphies in this part of phylospace are weak and rather unconvincing.

The results of their efforts were revealed at a news conference at the Museum on December 5, 1997, when a computer generated a sound said to be similar to one the dinosaur could have made 75 million years ago.
Robert Sullivan and Williamson, with support of the Dinosaur Society, published a formal scientific description and analysis of the new specimen as NMMNH&S Bulletin 15, A New Skull of Parasaurolophus (Dinosauria: Hadrosauridae) from the Kirtland Formation of New Mexico and a revision of the genus in 1999.
After hearing the computer-generated sound, Dr. Williamson speculated that it could have been so distinctive that dinosaurs of the same species could have recognized each other.
