This shows that caseid synapsids
were much more ancient than previously documented in the fossil record.
1996): First record of a basal synapsid
("mammal-like reptile") in Gondwana.
Quantitative comparison of ontogenetic and phylogenetic character changes in the synapsid
mandible and auditory region.
This single genus of synapsid
, a mammal-like reptile, populated much of Earth for 5 million years.
Among the reptilian ancestors of mammals, turbinal ridges appear to go back as far as early pelycosaurs, the oldest (Late Carboniferous and Early Permian Periods) and most primitive group of synapsid
Niassodon mfumukasi is the first new genus (and species) of a fossil vertebrate from Mozambique, and its holotype (name-bearing specimen) is a rare example of a basal synapsid
that preserves the skull and much of the skeleton together.
