The weeks #Lego #FossilFriday is #Plesiosaurus
In 1821, Henry De la Beche and William Conybeare name a fragmentary fossil Plesiosaurus.
In December 1823, Mary Anning finds relatively complete fossil of Plesiosaurus.
In 1824, Conybeare used Annings fossil as the Type species, since it was far more complete than his originals.
For many years additional fossils were found in the Lias Group until the cessation of quarrying activities in the Lias Group, early in the 20th century.
