Abstract

A fossil goniasterid (Asteroidea, Echinodermata) from the lower Lutetian glauconitic sands of the Authevernes-Vesly quarry (Eure, France) defines a new species, Autavesniaster wozniaki gen. et sp. nov. This is the first discovery of a nearly complete starfish fossil from the Eocene of the Paris Basin, whereas isolated marginal plates are relatively common in these deposits. This fragmentary material is often identified as “Teichaster” poritoides (Des Moulins, 1832) in the literature and institutional paleontological collections. A review of these isolated marginals reveals that the name “Teichaster” poritoides also includes remains of Autavesniaster wozniaki gen. et sp. nov., Metopaster sp., “Metopaster” besanconi Valette, 1925, and “Pycinaster” grignonensis Valette, 1924. The available material for these species remains insufficient to revise the generic attributions. Although “Teichaster” poritoides is widely reported across Europe, the name should be restricted to a species that appears to be endemic to the Paris Basin in the Eocene.

一种新的goniasterid化石（astero总科，棘皮科），以及对巴黎盆地Lutetian地区隐藏的海星多样性的洞察（法国）

在Authevernes-Vesly采石场（Eure, France）下Lutetian海绿石砂中发现的一种goniasterid化石（Asteroidea, Echinodermata）定义了一个新物种，Autavesniaster wozniaki gen. et sp. 11 .这是在巴黎盆地始新世首次发现的几乎完整的海星化石，而孤立的边缘板块在这些沉积物中相对常见。在文献和机构古生物收藏中，这种碎片材料通常被认定为“Teichaster”poritoides （Des Moulins, 1832）。对这些孤立的边缘的回顾表明，“Teichaster”poritoides的名称还包括Autavesniaster wozniaki gen. et sp., Metopaster sp.，“Metopaster”besanconi Valette， 1925年和“Pycinaster”grignonensis Valette， 1924年的遗骸。这些物种的现有资料仍不足以修正属属归属。尽管“Teichaster”poritoides在欧洲被广泛报道，但这个名字应该仅限于始新世巴黎盆地特有的一种物种。
