Leaellynasaura amicagraphica
(Leaellyn's lizard)Etymology
Leaellynasaura is derived from "Leaellyn" (for Leaellyn Rich, daughter of the authors) and the Greek "saura" (feminine form of "sauros" which means "lizard"). Leaellyn once asked for her own dinosaur and got it in 1989!
The
species epithet,
amicagraphica, literally translates as "friend painting", from the Latin "amica" (friend), for the friends of the Museum of Victoria and "graphica" (painting), for the National Geo
graphic Society and their support of Australian paleontology.
Discovery
The remains of
Leaellynasaura were discovered in the Eumeralla Formation at Dinosaur Cove, Australia, by Tom Rich and Patricia Vickers-Rich in 1989.
The
holotype (NMV P185991) is a partial skull.
