They are among his many reptilian foes alongside other dragons such as Inhusrelun, the Hydras and the Mutant reptiles and are the second dinosaur on this wiki alongside those depicted in Invasion of the Reptiles.
In real life
In evolutionary terms, dinosaurs were the land-dwelling descendants of the archosaurs, egg-laying reptiles that survived the Permian/Triassic Extinction Event 250 million years ago. Technically, dinosaurs can be distinguished from the other creatures descended from archosaurs (pterosaurs and crocodiles) by a handful of anatomical quirks.
Chief among these was posture: dinosaurs had either an upright, bipedal gait (like that of modern birds), or, if they were quadrupeds, a stiff, straight-legged style of walking (unlike modern lizards, turtles, and crocodiles, whose limbs splay beneath them when they walk).
The Dinosaurs depicted in Defenders of Earth are prehistoric reptiles that are enemies of both the dragon Firroth and many of his allies; apart from their appearances, there are a number of differences between these dinosaurs and those depicted in Invasion of the Reptiles:
For one, the dinosaurs depicted in Defenders of Earth have far more original names such as the Torvoplosaura and are almost always land based with some mutations. These dinosaurs also appear to be far more uniform in the sense that they are also always antagonistic and carnivorous while the dinosaurs from Invasion of the Reptiles are both carnivorous (only in Invasion of the Reptiles) and herbivorous (only in the World War X series while the carnivores still exist).
These types of dinosaurs also don't appear to have much powers like the other reptiles in the series, except massive intelligence which is possessed by various other animals in literature be they dragons or genetically mutated animals like the other antagonists featured in Defenders of Earth as well as the foxes depicted in Bounder and the Time Lord and Battle of the Foxes, the last two stories of the Surgeon stories; at least, the final two stories in the first revived series.
