ALLOSAURIDAE Meaning and
Definition
-
Allosauridae is a taxonomic family of theropod dinosaurs that existed during the Late Jurassic period, approximately 155 to 145 million years ago. It represents a group of carnivorous dinosaurs within the larger clade Allosauroidea. The family Allosauridae is characterized by a variety of common anatomical features shared among its members.
These dinosaurs were large-bodied and bipedal, with strong forelimbs and sharp, recurved teeth adapted for predation. They possessed substantial skulls with prominent crests, along with well-developed hind limbs that allowed for swift locomotion. Allosauridae exhibited a range of sizes, with some individuals reaching lengths of up to 12 meters (40 feet) or more.
Allosaurids were formidable predators within their ecosystems, and they likely occupied a position near the top of the Late Jurassic food chain. They were likely opportunistic hunters, capable of taking down a wide range of prey, including other dinosaurs. Fossil evidence suggests that they were agile and active predators, with a combination of strength, speed, and advanced senses allowing them to become successful apex predators.
The classification of specific species within Allosauridae is still a subject of ongoing research and debate, as new fossils and anatomical analyses continue to shed light on their evolutionary relationships. However, well-known examples of allosaurids include Allosaurus fragilis, Saurophaganax maximus, and Epanterias amplexus.
Etymology of ALLOSAURIDAE
The word "Allosauridae" has its etymology rooted in Ancient Greek. It is composed of two parts: "allo", meaning "other" or "different", and "sauridae", which is derived from "sauros", meaning "lizard". So, "Allosauridae" can be translated to mean "different lizard" or "other lizard". This term is used to refer to a family of large theropod dinosaurs that lived during the Jurassic Period.
