Veryhachium mensula
Veryhachium mensula Wetzel, 1933b, p.49–50, pl.4, fig.32 ex Downie and Sarjeant, 1965, p.151.
Originally Hystrichosphaera, subsequently Hystrichosphaeridium, thirdly (and now) Veryhachium. This combination was not validly published in Downie and Sarjeant, 1963 since these authors did not fully reference the basionym.
Holotype: O. Wetzel, 1933, pl.4, fig.32
Age: Late Cretaceous.
