Definitions

Ancodonta is a term that refers to a group of extinct bivalve mollusks that lived during the Mesozoic era. These mollusks were characterized by their asymmetrical shells, which lacked teeth and hinges. The term “Ancodonta” comes from the Greek words “an” meaning without, and “kondylos” meaning hinge.

Origin

Ancodonta is believed to have originated during the Triassic period, around 250 million years ago. These mollusks were widespread during the Jurassic and Cretaceous periods, but they eventually became extinct at the end of the Cretaceous period, around 65 million years ago.

Meaning in different dictionaries

In the Merriam-Webster Dictionary, Ancodonta is defined as “an extinct group of bivalve mollusks lacking a hinge and teeth and having an asymmetrical shell.” The Oxford English Dictionary defines Ancodonta as “a genus of bivalve mollusks characterized by an asymmetrical shell and lacking teeth and a hinge.”

Associations

Ancodonta is associated with the Mesozoic era and is often studied by paleontologists to better understand the evolution of bivalve mollusks. These mollusks are also associated with marine environments, as they lived in shallow seas and estuaries.
