gracilisuchus造句

• Erected in 1993, the clade usually contains early crurotarsan taxa like Poposauridae and " Gracilisuchus ".
• Other pseudosuchians thought to be closely related to crocodylomorphs include " Gracilisuchus " and possibly " Erpetosuchus ".
• Below is a cladogram after the exclusion of " Gracilisuchus " and " Turfanosuchus " ( Avemetatarsalia, Loricata and Poposauroidea have been collapsed ).
• While " Erpetosuchus " is widely accepted as the closest relative of crocodylomorphs, the relationship of more basal taxa like " Gracilisuchus " and " Ticinosuchus " are unclear.
• In most recent analyses, " Yonghesuchus " has been recovered as in a well supported clade, the Gracilisuchidae within the Pseudosuchia, along with " Gracilisuchus " and " Turfanosuchus ".
• The exclusion of " Gracilisuchus " and " Turfanosuchus " results in a more resolved topology, placing Erpetosuchidae at the base of Suchia as the sister taxon of aetosaurs plus " Revueltosaurus " clade.
• "' Suchia "'is a clade of archosaurs that includes all pseudosuchians except for the Gracilisuchus stipanicicorum ", and " Crocodylus niloticus " ( the living Nile crocodile ) by Nesbitt ( 2011 ).
• Erpetosuchidae formed a polytomy or unresolved evolutionary relationship with several other archosaur groups, including Avemetatarsalia, Ornithosuchidae, Aetosauria and " Revueltosaurus ", " Ticinosuchus " and Paracrocodylomorpha, " Gracilisuchus ", and " Turfanosuchus ".
• The removal of " Gracilisuchus " and " Turfanosuchus " from the analysis resulted in Erpetosuchidae nesting within the clade Suchia as the sister-taxon of Aetosauria plus " Revueltosaurus " clade, but not as a sister taxon of Crocodylomorpha as had previously been proposed.
