Abstract

ABSTRACT Conidae is a diverse family of carnivorous marine gastropods. They rapidly diversified during the Miocene and now they inhabit tropical and subtropical seas. Here we attempt to provide the first inventory of fossil conids from the late Miocene of Crete (Greece). This paper deals with the genera Conilithes and Conus (Kalloconus) da Motta, 1991 and will be followed by papers presenting other genera of the family. Using UV light, we described the residual colour patterns of eleven species, of which three are new: Conilithes herodus n. sp., Conus (Kalloconus) helladicus n. sp and Conus (Kalloconus) asterousiaensis n. sp. One species is in open nomenclature: Conilithes sp.. Six species are first recorded in the late Miocene of Crete: Conilithes brezinae (Hoernes & Auinger, 1879), Conilithes striatulus (Brocchi, 1814), Conus (Kalloconus) neumayri Hoernes & Auinger, 1879, Conus (Kalloconus) hendricksi (Harzhauser & Landau, 2016), Conus (Kalloconus) gulemani Erünal-Erentöz, 1958 and Conus (Kalloconus) letkesensis (Harzhauser & Landau 2016). Conilithes antidiluvianus (Bruguière, 1792) is the only species already recorded by past Greek authors. Firstly, our study reveals that only two species are restricted to the late Miocene of Crete (Conilithes herodus n. sp. and Conus (Kalloconus) helladicus n. sp.). Secondly, we found deep relationships with the conid assemblage from the Langhian of Paratethys (six shared species). This result could be interpreted as a conid fauna, present and widely distributed since the Langhian-Serravallian in both the Paratethys and the eastern Proto-Mediterranean. This fauna disappeared from Paratethys during the Serravallian, but probably persisted in the eastern Proto-Mediterranean, as suggested by the relationships with the Serravallian of Turkey and the Tortonian of Crete (this work). On the other hand, the weak relationships with the late Neogene of Italy might be biased because, for the comparison with Italian faunas, we used works that illustrated Conidae without UV light.

克里特岛（希腊）的中新世晚期锥虫科（软体动物：腹足目）。第1部分：Conilithes Swainson属，1840年和Conus（Kallocinus）da Motta属，1991年

摘要锥科是一个多样的海洋腹足类食肉动物科。它们在中新世期间迅速多样化，现在栖息在热带和亚热带海域。在这里，我们试图提供克里特岛（希腊）中新世晚期的第一批锥状化石。本文涉及Conilithes属和Conus（Kallocinus）da Motta属，1991年，随后将发表论文介绍该科的其他属。利用紫外线，我们描述了11个物种的残留颜色模式，其中3个是新物种：锥藻属herodus n.sp.、锥藻属helladicus n.sp和锥藻属asterousiaensis n.sp。一个物种是开放命名的：锥藻。6个物种首次记录在克里特岛中新世晚期：短叶锥藻科（Hoernes&Auinger，1879），条纹锥虫（Brocchi，1814），锥虫（Kalloconus）neumayri Hoernes&Auinger，1879，锥虫hendricksi（Harzhauser&Landau，2016），锥菌（Kalloconos）gulemani Erünal Erentöz，1958和莱特克斯锥虫（Harzhauser&Landau 2016）。Conilithes antidilvianus（Bruguière，1792）是过去希腊作者记录的唯一物种。首先，我们的研究表明，只有两个物种被限制在克里特岛中新世晚期（Conilithes herodus n.sp.和Conus（Kallocinus）helladicus n.sp.）。这一结果可以被解释为锥状动物群，自Langhian Serravallian以来，在Paratethys和东原地中海都存在并广泛分布。该动物群在塞拉瓦利亚期从副特提斯消失，但可能在原地中海东部持续存在，正如与土耳其塞拉瓦利亚和克里特岛托托尼亚的关系所表明的那样（本工作）。另一方面，与意大利晚第三纪的微弱关系可能是有偏见的，因为为了与意大利动物群进行比较，我们使用了没有紫外线的Conidae插图。
