在阿尔伯塔中西部落基山脉的费尔尼组的扑克芯片页岩中发现了一个Paraplesioteuthis hastata(Miinster)的单一标本,其时代为早托阿尔西期(侏罗纪)。它是北美侏罗纪岩石中第一个代表性的条虫目,并显着扩大了原条虫亚目的地理范围,以前只知道在欧洲的一般地区。
A single specimen of Paraplesioteuthis hastata (Miinster) from the Poker Chip Shale, Fernie Formation in the Rocky Mountains of central western Alberta is of early Toarcian (Jurassic) age. It is the first representative of the order Teuthida in Jurassic rocks from North America and significantly expands the geographic range of the suborder Prototeuthina, previously known only from the general area of Europe.
