Exempel på hur man kan använda ADAPIFORMS i en mening

• Prosimians are a group of primates that includes all living and extinct strepsirrhines (lemurs, lorisoids, and adapiforms),.
• Rose (1995) suggests that early adapiforms and omomyiforms shared a common ancestor dating to the Thanetian age.
• Pelycodus is placed within adapiforms because of its annular ectotympanic, small eyes, non-elongated tarsus and numerous premolar and molar crests and within Notharctinae because of its four premolars, unfused mandible, a hypocone derived from the postprotocingulum and a lacrimal bone within the orbit.
• Although the anterior dentition of azibiids is unknown, they may have possessed a toothcomb, indicating an ancient stem lineage of lemuriform primates in Africa, possibly descended from an early Asian branch of adapiforms such as a primitive branch of cercamoniines predating Donrussellia (one of the oldest European adapiforms).
• In particular, it is distinct from the three main branches of primate found in Africa at the time - anthropoids, adapiforms and lemuriforms.
• This Afro-Arabian clade, which includes crown lemuriforms and possibly the disputed azibiids, excludes the Holarctic adapiforms and may be descended from an early Asian branch of adapiforms such as a primitive branch of cercamoniines predating Donrussellia (one of the oldest European adapiforms).
• Like the strepsirrhine adapiforms, omomyids were diverse and ranged throughout Eurasia and North America.
• Key features differentiating sivaladapids from other adapiforms include upper molar shearing crests, the twinning of the hypolconulid and entoconid on the lower molars, and a continuous lingual cingulum on the upper molars.
• Afradapis also differs from other caenopithecid adapiforms in their dental anatomy in the following ways: possession of tall and trenchant upper and lower third premolars, a variably present mesoconid on lower molars (usually on M1), a lack of metastylids on M1-3, and large hypocones and prehypocristae present on all upper molars.
• They were very small and were some of the earliest adapiforms, similar to cercamoniines but also sharing features with sivaladapids.
