Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs.
Sauropoda is a clade of dinosaurs that consists of roughly 300 species of large, long-necked herbivores and includes the largest terrestrial animals ever to exist. The first sauropod species were named in 1842 by Richard Owen, though at the time, he regarded them as unusual crocodilians.
The bi- or trilaminar yolk sac of viviparous sauropsids is loosely associated with the secretory uterine epithelium and contributes to three subcategories of placentation: (a) the choriovitelline placenta, which also occurs in marsupial and eutherian mammals, (b) the widespread omphaloplacenta placenta and (c) the omphalallantoic placenta, which...
