Isaberrysaura

Isaberrysaura is an extinct genus of stegosaurian ornithischian dinosaurs from the Middle Jurassic Los Molles Formation of Patagonia, Argentina. The genus contains a single species, I. mollensis, described by Salgado in 2017 based on a single specimen. Although initially classified as a basal neornithischian, subsequent analyses have allied it with the Stegosauria as the morphology of its skull resembles those of other members of the group.

== Discovery == thumb|left|Map of the Isaberrysaura Type locality (biology)|type locality The Isaberrysaura holotype specimen, MOZ-Pv 6459, was discovered in the marine to deltaic sediments of the Los Molles Formation, which is of Bajocian age, by Isabel Valdivia Berry, who is honoured in the generic name. The specimen consists of a partial skeleton (the postcranial material of which is still unprepared) with a nearly complete skull, six cervical vertebrae, fifteen dorsal vertebrae, a sacrum with a partial ilium and apparently complete pubis, nine caudal vertebrae, part of a scapula, ribs, and other unidentifiable fragments.
