FIGURE 3. Trichogypsia alaskensis n. sp.: (A) the two fragments of the holotype. The left fragment shows the upper side of the sponge with (micro-)conules. The left fragment shows the smoother bottom-side of the sponge with still adhering fragments of the substrate. Scale at bottom in mm. (B) Section parallel to the upper surface. Darker spots are conules of the surface constructed by groups of diactines. Scale bar is 100 µm. (C) Section parallel to the bottom side. Diactines are arranged more parallel to the smooth surface. Scale bar is 100 µm. (D) Section perpendicular to the surface. Top right are the diactines constructing the surface conules. Below is the choanosome of the sponge and at the lower left the smooth surface of the bottomside is visible. Scale bar is 100µm. (E) Section perpendicular to the surface with a better view of the architecture of the surface conules. Scale bar is 100 µm.
