ALT Top: Grid including illustrations (top row) and photographs (bottom row) of Palaeozoic echinoid fossils demonstrating examples of 5 taphonomic grades used in the paper. Left to right: TG1, MCZ:IP:103620, disarticulated spine and interambulacral plate of the archaeocidarid Archaeocidaris sp.; TG2, LACM 2020.1, pile of disarticulated interambulacral plates and spines from Archaeocidaris sp.; TG3, MCZ:IP:101936, fragment of a test of the palaechinid Maccoya intermedia showing ambulacral and interambulacral plates; TG4, YPM 26552, denuded test of the lepidesthid echinoid Lepidesthes colletti; TG5, NHMUK Pal E 76888, holotype of Archaeocidaris whatleyensis, an articulated test preserved with covering spines; scale bars (with photographs) are 1 cm. Bottom: Coloured plot showing the temporal distribution of taphonomic grades from the Ordovician (on the left) to the Permian. Vertical axis represents frequency of occurrence.
