Both synapsids and sauropsids are amniotes meaning the fetal forms are nurtured by a complex series of nutrients and membranes until they mature enough to breathe air and walk the world independentlyFor synapsids this involves a womb placental mammals or a pouch marsupials Sauropsids lay eggs Synapsids and sauropsids are thought to have evolved from amphibians at...

What are Basal Amniotes with picture

Basal amniotes evolved from reptiliomorphs amphibians living approximately 340 million years ago which resembled reptil Although called reptiliomorphs this group is the common ancestor of both mammals and reptil One of the first known basal amniotes is Casineria a small 15 cm 6 in animal which superficially resembled a tiny lizard discovered in 1992 but only described in 1999...

Sauropsida Dinopedia Fandom

In 1956 DMS Watson observed that sauropsids and synapsids diverged very early in the reptilian evolutionary history and so he divided Goodrich s Protosauria between the two groups He also reinterpreted the Sauropsida and Theropsida to exclude birds and mammals respectively making themparaphyletic unlike Goodrich s definition...
