Description
Raptors were carnivorous dinosaurs, members of the family Dromaeosauridae ("running reptiles" - in Greek), which lived mainly during the Cretaceous period, about 143-66 million years ago. They were small to medium-sized feathered dinosaurs that walked on two legs and hunted using speed, sharp claws and serrated teeth. They may have hunted in groups. Among the famous features of raptors is the oversized claw on their feet, probably used to attack prey and climb trees. The family is believed to Dromaeosauridae is believed to share a common ancestor with modern birds.
Famous raptor genera include: Velociraptor, Utahraptor and Deinonychus. In Morocco, there was a species of raptor whose teeth are frequently found by local fossil hunters. Unfortunately, in the case of the Moroccan raptor, Only teeth have been discovered, so its exact appearance and other physiological characteristics can only be theorized based on its belonging to the family Dromaeosauridae.
Raptors' teeth were sharp and serrated, optimized for tearing flesh. As with other reptiles, raptors replaced their teeth very frequently during their lives, even weekly.
Abelisaurs (“Abel’s lizard” – the family Abelisauridae) were a group of medium-sized, predatory theropod dinosaurs that lived mainly during the Cretaceous period (about 145 million years ago to 66 million years ago) in what is now South America and Africa.
Abelisaurs were bipedal carnivores that reached between 5 and 12 meters in length, depending on the species. They had two very short hands, with 4 fingers on each hand, and a tall and short skull, which could have various ornaments (hard ridges on the snout and above the eyes, horns, bony protrusions, etc.). These ornaments probably had a role in intimidation or identification of members of the species.
