CT Scan of paralectotype AM J. 30961 of Tripneustes australiae (Tenison-Woods, 1878) (Echinodermata: Echinoidea) – Supplementary material to McLaren et al. (2023): "Hidden in plain sight: Tripneustes kermadecensis (Echinodermata: Echinoidea) is a junior synonym of the eastern Australian sea urchin Evechinus australiae described in 1878"
MicroCT scan of lectotype specimen AM J. 30961 of Tripneustes australiae (Tenison-Woods, 1878) (Echinodermata: Echinoidea: Toxopneustidae) in the Australian Museum (Sydney) collection. Originally described as Evechinus australiae and subsequently registered together with two other syntype specimens under the number AM J. 1099. Lot subsequently split into three separate inventory numbers, each containing the remains of a single individual (AMJ. 30960, J. 30961, and J. 1099). Lectotype designation and redescription by McLaren et al. (2023).
