DIPTERYGIANS Meaning and
Definition
-
Dipterygians are a group of prehistoric fishes that existed during the Permian period, around 300 to 250 million years ago. These fishes were part of a larger group known as actinopterygians, which includes most living fishes today. The name "dipterygians" derives from the Greek words "di," meaning two, and "pteryx," meaning wing, due to their unique physical characteristics.
One defining feature of dipterygians was their double-lobed tail fin, which consisted of two distinct fin lobes at the back of their bodies. This tail structure distinguished them from other types of fishes during that time period. It is believed that this anatomical adaptation provided them with enhanced maneuverability and swimming capabilities, allowing them to thrive in various aquatic environments.
Dipterygians also possessed a set of paired pectoral fins, which were situated just behind their heads. These fins are thought to have played a crucial role in their ability to control their movements and maintain stability in the water. Additionally, they had a cartilaginous skeleton, as opposed to a bony skeleton like many other fishes.
Although dipterygians are extinct today, their presence in the fossil record offers valuable insights into the evolution and diversity of early fishes. Their distinguishing characteristics and the adaptations they developed throughout their existence contribute to our understanding of the history and biology of fish species.

Etymology of DIPTERYGIANS
The word "Dipterygians" is derived from two Greek roots: "di" meaning two, and "pterygion" meaning wing. In zoology, "dipterygians" refer to a group of fish known as the bony-tongued fishes, which have a distinct feature of having two separate dorsal fins. The term was coined based on the Greek roots to describe this characteristic.
