Schoor, D.I.E., Donovan, S.K. & Webster, G.D. 12 September 2019. Camptocrinus Wachsmuth & Springer or Neocamptocrinus Willink? Distinctive crinoid columnals from the Permian of Timor. Alcheringa 44, 56–63. ISSN 0311-5518 Only one nominal species of the monobathrid camerate crinoid Camptocrinus Wachsmuth & Springer is known from the Permian of Timor, namely Camptocrinus indoaustralicus Wanner. The varied morphologies of disarticulated columnals may be due to variation within the xenomorphic column of this species, the presence of one or more additional species and/or the co-occurrence of the monobathrid Neocamptocrinus Willink. Herein, columnals are grouped into those with a strong elliptical shape; those with an inflated and oval outline; and those intermediate between these two extremes. A single specimen is encrusted by the auloporid tabulate coral Cladochonus? sp. Even separating Camptocrinus and Neocamptocrinus on the basis of more complete specimens is problematic. Neocamptocrinus is defined by its numerous small plates in an extended tegmen, which is commonly lost or concealed. Both Camptocrinus and Neocamptocrinus have three small anals in the base of the tegmen immediately above the large single primanal in the radial circlet. The column tapered to a distal point in both genera and was anchored to the substrate by a radicular runner. It may be that the two genera are one, but, if not, Neocamptocrinus is strictly Permian and limited to Tethys. Debbie I.E.

Camptocrinus Wachsmuth & Springer 还是 Neocamptocrinus Willink？来自帝汶二叠纪的独特海百合柱状体

Schoor, DIE, Donovan, SK & Webster, GD 2019 年 9 月 12 日。 Camptocrinus Wachsmuth & Springer 还是 Neocamptocrinus Willink？来自帝汶二叠纪的独特海百合柱状体。阿尔切林加 44、56-63。ISSN 0311-5518 在帝汶二叠纪，仅已知一种名为 Camptocrinus indoustralicus Wanner 的单科动物海百合 Camptocrinus Wachsmuth & Springer。脱节柱状动物的不同形态可能是由于该物种的异形柱内的变化、一种或多种其他物种的存在和/或单节肢动物 Neocamptocrinus Willink 的共同出现。在此，柱状柱被归为椭圆形强的柱状柱；那些具有膨胀和椭圆形轮廓的人；以及介于这两个极端之间的那些。单个标本被 auloporid 板状珊瑚 Cladochonus 包裹着？sp. 即使在更完整的标本的基础上分离 Camptocrinus 和 Neocamptocrinus 也是有问题的。Neocamptocrinus 的定义是它在延伸的 tegmen 中的众多小板，通常丢失或隐藏。Camptocrinus 和 Neocamptocrinus 在 tegmen 的基部都有三个小肛门，紧挨着径向环中的大单个原始动物。柱子在两个属中都逐渐变细到远端点，并通过根状转轮锚定在基质上。这两个属可能是一个属，但如果不是，则 Neocamptocrinus 严格属于二叠纪，仅限于特提斯。Debbie IE Schoor [dieschoor@gmail.com], Perobahout 2, 2719 KR Zoetermeer, 荷兰；Stephen K.
