Exempel på hur man kan använda ENANTIORNITHEANS i en mening

• The Enantiornithes, also known as enantiornithines or enantiornitheans in literature, are a group of extinct avialans ("birds" in the broad sense), the most abundant and diverse group known from the Mesozoic era.
• In Hartman et 2019 supplementary it is noted that the construction of the tibiotarsus is more typical of enantiornitheans than ornithurine birds Nanantius is tentatively recorded as part of a clade closely related to Vorona, Grabauornis and Yungavolucris.
• As in most enantiornitheans, no hypotarsus (a wide ridge on the back of the tarsometatarsus) is present.
• Inferring from the features of other enantiornitheans, Concornis also likely possessed a long, narrow pygostyle which connected to a single pair of ribbon-like tail feathers, rather than a fan-like tail of pennaceous feathers as in modern birds.
• However, Bauxitornis can be distinguished from these other enantiornitheans due to having a shortened metatarsal II (the innermost preserved midfoot bone) without a tubercule (scarred bump) for the M.
• This is entirely unlike the long rod- or spear-like pygostyles known in other enantiornitheans, as well as confuciusornithids and sapeornithids.
