Abstract: Chaetognaths, with their characteristic grasping spines, are the oldest known pelagic predators, found in the lowest Cambrian (Terreneuvian). Here we describe a large stem chaetognath, Timorebestia koprii gen. et sp. nov., from the lower Cambrian Sirius Passet Lagerstatte, which exhibits lateral and caudal fins, a distinct head region with long antennae and a jaw apparatus similar to the Amiskwia sagittiformis. Amiskwia has previously been interpreted as a total-group chaetognathiferan, either as a stem-chaetognath or gnathostomulid. We show that T. koprii shares a ventral ganglion with chaetognaths to the exclusion of other animal groups, firmly placing these fossils on the chaetognath stem. The large size (up to 30 cm) and gut contents in T. koprii suggest that early chaetognaths occupied a higher trophic position in pelagic food chains than today2024-01-01T00:00:00ZKorea-Norway Partnership Cooperation for High-resolution Mapping of Ice Sheet Margin, AntarcticaLee, Won Sanghttps://repository.kopri.re.kr/handle/201206/147612023-12-04T02:21:54Z2023-11-27T00:00:00ZTitle: Korea-Norway Partnership Cooperation for High-resolution Mapping of Ice Sheet Margin, Antarctica
