Description

A massive encrusting specimen, of which only a fragment was collected ca 3 mm long by 2 mm wide. The sponge was roughly cone-shaped, with an osculum on top of the ‘chimney’. The surface is velvety. The specimen was creamy white when alive, but turned yellowish beige when preserved in ethanol (Fig. 8A).

Skeleton

Due to the dimensions of the collected fragment it was not possible to produce a thick section. Spicules are thin oxeas, with a wide range of sizes (Fig. 8B), measuring: 71.4– 103.8 –136.1 ±10.26 ×0.1– 3.1 – 6.1± 1.27 µm (N=61).
