ABSTRACT Jinonicella kolebabai Pokorný, 1978, a small problematic “mollusc” of unknown origin is described from the early Silurian (early to mid Llandovery) of east Siberia. This is the first record of Jinonicella from Siberia. Previous Silurian records of Jinonicella were from the late Llandovery (Telychian) of North America and the Wenlock to Ludlow of Europe (Bohemia, Gotland and the Carnic Alps of Austria). Jinonicella shows a wide range of geographic and stratigraphic distribution. It was reported from three palaeocontinents and several smaller terranes. It also demonstrates adaptation to different environments from shallow to deep-water settings, and spans several climatic zones from equatorial to temperate belts. The wide distribution and adaptation to a broad range of environments allow Jinonicella to subsist for about 100 my, i.e., from the Middle Ordovician to the Late Devonian surviving through two major extinction events.

来自东西伯利亚早期志留纪的有问题的软体动物 Jinonicella 的新数据

摘要 Jinonicella kolebabai Pokorný，1978 年，描述了一种起源不明的小型问题“软体动物”，它来自东西伯利亚的早志留纪（兰多维早期到中期）。这是西伯利亚稗子的第一个记录。以前志留纪吉诺氏菌的记录是从北美的兰多维（特里奇亚）晚期和欧洲的文洛克到拉德洛（波西米亚、哥特兰和奥地利的卡尔尼克阿尔卑斯山）。Jinonicella 具有广泛的地理和地层分布。据报道，它来自三个古大陆和几个较小的地体。它还展示了对从浅水到深水环境的不同环境的适应，并跨越从赤道到温带的几个气候带。广泛的分布和对广泛环境的适应使得金诺克氏菌能够生存约 100 米，即，
