Villegas-Martín et al. (2025) identify a fossil wood specimens from the La Meseta Formation (Antarctica), preserved with a boring interpreted as likely produced by a large-bodied member of the genus Kuphus, and representing possible evidence of wood colonization by large-bodied shipworms in the Antarctic Peninsula during the Eocene.^[125]
