ESSAY

Tall osteoderms lined the back of this unusual
sauropod.
They seem to have been mobile, a case of parallel evolution with stegosaurs. The samllest were leaf-shaped, while the largest ones were split into halves, each half bearing an outward-pointing spike.
Agustinia may be related to titanosaurs or to rebbachisaurids.
