Abstract

New specimens of Gabelia pedunculus Rigby and Murphy, 1983, and of the new species Gabelia giganta and Gabelia fascicula are described from the Siluro-Devonian(?) Roberts Mountains Formation from Loomis Creek Canyon in the Snake Mountains, northeastern Elko County, Nevada. Stalk fragments of G. pedunculus are similar to the holotype from the northern Roberts Mountains, Eureka County, Nevada. Gabelia giganta n. sp. is a large species with skeletal elements in the stalk twice the size of elements in G. pedunculus. Gabelia fascicula n. sp. is based on thick-walled, cup-like upper parts where a gastral layer of coarse, diagonally oriented spicules contrasts to a dermal layer of regular vertical and horizontal bundles of hexactine-based spicules of at least two orders around parietal gaps. The specimens are all part of a probably transported seafloor assemblage.
