Description

Eromangateuthis soniae is known from several gladii found in the Allaru Formation of Queensland^[1][2] and a potential gladius from the Northumberland Formation of British Columbia.^[3] It was originally described in 1993 as Boreopeltis soniae,^[2] but was moved to its own genus in 2019 based on multiple differences between it and the type species of Boreopeltis.^[1] The generic name is derived from the Eromanga Basin in which it was discovered and the Ancient Greek teuthís (τευθίς, 'squid').^[1] One gladius suggests it had a mantle length of 1.2 meters.^[1] This makes Eromangateuthis the largest known plesioteuthidid, with a mantle length over twice as long as the second largest, Boreopeltis ifrimae.^[4]
