Ontogeny of the Ammonoid Genus Dactylioceras from Northeastern Russia 2000 (original) (raw)

The understanding of phylogenetic relationships within Anolis has seen great advances in the past ten years due to a significant number of phylogenetic studies based primarily on molecular data. Despite this large effort, there is still a large void of information regarding mainland species. According to recent phylogenies (Poe, 2004; Nicholson et al., 2005) mainland species belong to two non-nested clades: an unnamed clade (designated the M2 clade by Pinto et al. [2008]), which includes the deeply nested Central and South American species derived from Greater Antillean ancestors and Dactyloa (same as the latifrons series of Etheridge [1959] and the M1 clade of Pinto et al. [2008]), which represents one of the early branches in Anolis and includes species from Central and South America and the Lesser Antilles.
