The fossils of Eoprephasma were studied by Bruce Archibald and Sven Bradler before being deposited to the Thompson Rivers University, a public university which was established in 1970, and the Burke Museum of Natural History and Culture.
Eoprephasma is an extinct genus of stick insect in the superfamily Susumanioidea known from a group of Eocene fossils found in North America. All the insects were first studied by Canadian entomologist S Bruce Archibald and German entomologist Sven Bradler, with their 2015 type description of the new genus and species being published in the journal Canadian Entomology. The counterpart specimen F-1099 is also in the Thompson Rivers University collections, while the part side, PB-3825 is at the Burke Museum of Natural History and Culture.
