The Anthropocene is characterized in geological terms by the stratigraphic inscription of human impact. Donna Haraway refigures the Anthropocene as a boundary event, the surpassing of which requires the formation of trans-genealogical kinships between biotic and abiotic actors. In the interest of such kinships, we turn our attention to plastic, a biogenic material derived from ancient zooplankton and algae, and, as we show, one with its own vibrant life history and phylogeny. Taking an approach informed by Haraway’s “kin-making” and Nicolas Nova’s The Bestiary of the Anthropocene, this article is a taxonomic description of Plasticus gen. nov. sacculi sp. nov., a new deep-sea “species.” Based on a real observation of a plastic bag in the deep sea, we describe the distribution, life history, and phylogeny of Plasticus sacculi.

人类世的地质学特征是人类影响的地层铭文。唐娜·哈拉维将人类世重新定义为一个边界事件，超越它需要在生物和非生物参与者之间形成跨谱系的亲缘关系。为了这种亲缘关系，我们将注意力转向塑料，这是一种源自古代浮游动物和藻类的生物材料，正如我们所展示的，它具有自己充满活力的生命史和系统发育。本文采用哈拉维的“亲属制造”和尼古拉斯·诺瓦的《人类世动物寓言》的方法，对塑料属进行了分类学描述。十一月萨库利水产养殖十一月，一个新的深海“物种”。基于对深海塑料袋的真实观察，我们描述了 Plasticus sacculi 的分布、生活史和系统发育。
