PISANOSAURUS MERTII
"Carlos Merti's Juan Pisano's Lizard"
Casamiquela, 1967
Length: 1m (3.3ft)
Weight: 9.1kg (20lbs.)
Location: San Juan, Argentina
Era: Carnian age, upper Triassic (228 million years ago)
Classification:
Dinosauria
Ornithischia
Pisanosauridae
Notes:
Pisanosaurus's importance as a fossil, being the earliest and basalmost Ornithischian dinosaur known, is equaled only by the paucity of its known remains--worsened by the fact that parts of what little was found have been lost due to decisions made in preparation and other assorted damage.
