ANKYLOSAURIDAE Meaning and
Definition
-
Ankylosauridae is a scientific term used in paleontology to classify a family of herbivorous dinosaurs that lived during the late Cretaceous period, roughly 68 to 66 million years ago. The word "ankylo" originates from the Greek word meaning "curved" or "bent," while "sauridae" comes from the Latin word "saurus" meaning "a lizard." Together, Ankylosauridae refers to a group of reptiles known for their unique physical characteristics and evolutionary adaptations.
Members of the Ankylosauridae family were characterized by their heavily armored bodies, with bony plates called osteoderms embedded in their skin. These osteoderms formed a protective shield over their backs and sides, providing defense against predators. Additionally, ankylosaurids had bony knobs or spikes projecting from their bodies as further protection.
Their distinctive feature was a large, club-like tail, formed by a fusion of vertebrae, which they used as a powerful weapon to defend themselves from predators. This tail club could cause significant damage when swung, possibly fracturing the bones of attackers.
Ankylosauridae were typically quadrupedal, meaning they walked on all fours, and possessed short, stocky limbs. They had broad skulls with small, leaf-shaped teeth that were specialized for grinding plant material. It is believed that these dinosaurs were mostly low browsers, feeding on low-growing vegetation, such as ferns and cycads.
Overall, Ankylosauridae constituted a diverse group of armored dinosaurs with various species having unique adaptations, enabling them to thrive in their environment and survive the Late Cretaceous period.
Etymology of ANKYLOSAURIDAE
The word "ankylosauridae" originates from two different sources: "ankylosaur" and "-idae".
1. The term "ankylosaur" comes from the Greek word "ankylos", meaning "crooked" or "curved", and the Greek word "sauros", meaning "lizard". It was coined in 1908 by American paleontologist Barnum Brown to describe a group of armored dinosaurs characterized by their heavily armored bodies, bony knobs, and club-like tails.
2. The suffix "-idae" is derived from the Greek word "ida", which signifies a "family". In taxonomy, the suffix "-idae" is added to the end of a word to indicate family classification. Therefore, "ankylosauridae" denotes the family classification of ankylosaurs, a group of armored dinosaurs.
