缅甸中始新世晚期邦塘组Paukkaungmeryx minutus(鲸偶蹄目,古鼷鹿科)新材料
New material of Paukkaungmeryx minutus(Cetartiodactyla,Archaeomerycidae)from the late Middle Eocene Pondaung Formation,Myanmar
摘要
Abstract
We describe here new dental material from the locality of Myaukse Kyitchaung(Pondaung Formation,central Myanmar)that we refer to the primitive Archaeomerycidae ruminant Paukkaungmeryx minutus Ducrocq et al.(2020).The upper molars are morphologically very similar to those of the holotype and exhibit only slight variations on features like the better development of buccal and lingual cingula.The lower teeth display primitive characters including a simple p4 and bunoselenodont lower molars that lack folds on the back of the trigonid wall.This additional material makes Paukkaungmeryx the second archaeomerycid in Pondaung known by upper and lower teeth material,and documents the apparently complex early evolution of the family.关键词
