  Dinosaurs - Tenontosaurus
Tenontosaurus (meaning "sinew lizard") was a very large (24 feet long and about 500 kg or 1 ton in weight) hypilophodontid that lived in the Aptian-Albian ages in the Lower Cretaceous period about 116-113 million years ago.
Although it probably ran on two legs, Tenontosaurus was large and bulky and probably spent most of its time on four legs, grazing.
Tenontosaurus was named in 1970 by John H. Ostrom and G. Meyer.

 Natural History Magazine | Feature
He later named the herbivore Tenontosaurus, or “sinew reptile.” His genus name for the theropod, Deinonychus, or “terrible claw,” was inspired by the large sickle-shaped claw it brandished on the second toe of each foot.
Tenontosaurus was a medium-sized herbivore (similar to the hadrosaurs, or duck-billed dinosaurs, which were so abundant later in the Cretaceous) that walked on two sturdy hind limbs, balancing its weight over the hips.
Similarly, if the Tenontosaurus had been killed by a larger predator-such as the unknown owner of the three-inch-long serrated teeth that occasionally crop up in the Cloverly formation—then whatever remained of the carcass would have been strewn around the area.

Tenontosaurus is a primitive iguanodontian, a basal member of the line that would lead to hadrosaurs (the famous "duck billed" dinosaurs).
Tenontosaurus is known from many good specimens, and is known from the mid-Cretaceous of the western U.S., about 100 million years ago.
It's very rare to see a drawing of Tenontosaurus in which Deinonychus is not feeding or attempting to feed on it, usually in a pack.

Tenontosaurus semble donc former un groupe intermédiaire entre le clade des « hypsilophodontoïdes » et celui des « iguanodontoïdes ».
The strip formed by the reunion of the exoccipitals is less expanded dorso-ventrally in Tenontosaurus tilletti than in the 'iguanodontoid' and 'hadrosauroid' clades.
Tenontosaurus may therefore represent an intermediate group between the 'hypsilophodontoid' and 'iguanodontoid' clades.

 Hypsilophodontia
Tenontosaurus is sometimes considered a basal Iguanodontian; Muttaburrasaurus is variously considered a basal Iguanodontian, a specialised Hypsilophodont, Camptosaurid, or an Iguanodontid.
It was more heavily-built and stouter of limb then most hypsilophodonts, and probably, like its bigger cousins Tenontosaurus and Muttaburrasaurus, or even a small iguanodontid, and capable of getting about on all fours.
Comments: distinguished by its unusually long tail (which may or may not have been an aid in swimming), Tenontosaurus has the misfortune to be continually portayed by dinosaur artists as being torn apart by a pack of hungry Deinonychus.

This collection of bodies might have been a chance result of nature, but one could easily imagine the small and vicious pack of Deinonychus surrounding the Tenontosaurus, leaping and slashing until the great creature was overcome by the persistence of its attackers.
During the struggle, a couple Deinonychus could have been killed by the thrashing of Tenontosaurus' tail, but in the end - the effective wolf-pack type hunting of the smaller dinosaur would have overcome the great herbivore's' resistance.

Found in the western and southwestern United States, Tenontosaurus was a large plant-eater that resembled Iguanodon.
Its tail was stiffened by ossified tendons that reinforced the tail vertebrae providing balance for its bipedal stance.
Because the teeth of Deinonychus have been found in the vicinity of Tenontosaurus remains, it is thought that Tenontosaurus might have been Deinonychus' prey.

 The Complete Dinosaur: Selected Excerpts
The frequent co-occurrence of these elements and the dearth of Deinonychus teeth in the vicinity of bones from other possible prey animals suggest that the herbivorous Tenontosaurus may have been the preferred prey of Deinonychus.
Thus the assemblage has been interpreted as the scavenged remains of a struggle between a large Tenontosaurus and a pack of the much smaller Deinonychus.
The presence of both Deinonychus and Tenontosaurus bones at the site suggests that the prey animal and members of the attacking Deinonychus pack were killed during the struggle and were subsequently consumed (Ostrom 1990; Maxwell and Ostrom 1995).

Iguanodontia: Basal Iguanodontia is a home for misfits, it seems; there is the hypsilophodont-like Rhabdodon and its allies, the "iguanodontid"-like Muttaburrasaurus, and the long-tailed oddball Tenontosaurus, among others.
The ordering is a bit controversial, and goes back and forth with which taxon is put at the base of Iguanodontia.
Long-tailed, tall-spined Tenontosaurus is known from dozens of specimens of all ages.

 Neoceratopsian teeth from the Lower to Middle Cretaceous of North America
In Tenontosaurus, the primary ridge is also prominent (OU 8-0-S3).
In contrast, in Tenontosaurus (OU 8-0-S3), the secondary ridges are few, and extend with equal prominence down the length of the crown.
Camptosaurus (UUVP 5946) is the only ornithopod in which the secondary ridges end prior to the base of the crown, but the indentations in teeth of this taxa become shallower nearer to the root, thus causing the termination of the ridges before the base of the crown.

The discovery of a nearly complete skeleton of Tenontosaurus tilletti and closely associated multiple shed teeth of the dromaeosaur Deinonychus antirrhopus provides evidence that may support the often repeated suggestion that Deinonychus was a pack-hunting predator.
The taphonomy of the specimen adds weight to the additional conclusion that Tenontosaurus was the specific food preference of the Deinonychus predator population.
Among theropods, the only other specific animals that have been found as unmistakable food objects are Bavarisaurus in Compsognathus and Coelophysis in Coelophysis.
