From dinoflaj2
"lairdii" Deflandre, 1946c, card 1112 ex Loeblich Jr., 1970, p.742. Holotype: Deunff, 1959, pl.8, fig.75, designated by Loeblich Jr. (1970, p.742). Originally Hystrichosphaeridium (name not validly published), subsequently Veryhachium. Taxonomic senior synonym: Veryhachium valiente Cramer, 1964, an acritarch species, according to Martin (1969, p.95), who believed Veryhachium lairdii to be the senior name. Taxonomic junior synonym: Veryhachium bromidense Loeblich Jr., 1970, an acritarch species, according to Turner (1984, p.142). The name Hystrichosphaeridium lairdii was not validly published in Deflandre (1946c) since that author did not provide a description. Age: Mid Silurian.
