Which group was first formed between Dinosaur Pile-Up and Enanitos Verdes?
Enanitos Verdes Enanitos Verdes (Literally "Little green dwarfs", roughly equivalent to the English phrase "Little green men") is a rock trio from Argentina, formed in 1979 in the city of Mendoza.
Carusioidea Carusioidea is a clade (evolutionary grouping) of lizards that includes the family Xenosauridae (knob-scaled lizards) from Central America and the extinct genus "Carusia" from the Late Cretaceous of Mongolia. It was named in 1998 after a sister-group relationship was found between "Carusia" and Xenosauridae. Phylogenetic analysis indicates that Carusioidea is the most basal clade within Anguimorpha. Features that help define Carusioidea include closely spaced orbits or eye sockets separated by fused frontal bones, a connection between the jugal and squamosal bones below the supratemporal arch, and a covering of bony osteoderms over the skull roof. Below is a cladogram showing the phylogenetic relationships of carusioids from Gao and Norell (1998):
