This showcase is dominated by a massive orange-brown fossil slab, roughly triangular with the longest side (1.65 m) vertical and the smaller sides to the right. The slab is extensively covered with fossils of ancient fish.
Just above the fossil slab, to the right, is a small, greenish-yellow (20 cm long) taxidermied Night Parrot, mounted on a short piece of tree branch.
On each side of the fossil slab, towards its top, are shallow display boxes. The box on the left holds six flat yellowish slabs of rock with distinct imprints of ancient insects, fish and plants. The box on the right holds four examples of marine invertebrates: two sponges looking like small brown shrubs, a pair of small crabs and a 19 cm circular flattened sea urchin, brown with a rough texture, and missing its spines.
On the left of the fossil slab, below the box containing the small fossils, is a goniometer. This instrument is made of polished brass and cast iron. It consists of a group of lenses that concentrate light into a fine beam and a telescope aimed at a central area where the mineral sample is placed. There is a protractor at the pivot. The goniometer has all manner of screws and attachments for making optical adjustments and for levelling the instrument.
On the right of the fossil slab, below the marine invertebrates display box, is a plinth on which sits a stone axe with wooden haft and a cylindrical glass jar containing, in liquid, a 35cm-long yellow-brown Common Seadragon. This fish looks somewhat like a large seahorse with its tail below and its head above a bulbous belly.
In front and below this plinth sits a group of five bright green, red, yellow and pink invertebrate sea creatures – but they are artificial, made of glass. And to their right lies a hard-cover book in a V-shaped cradle, held open at pages showing writing to the left and three marine specimens to the right.
On the front left of the showcase is a small plinth. At left is a fossil turtle skull, 24 cm wide. Next to it is another cylindrical glass jar containing a brownish spider, its long legs curled under its body, and a small piece of paper on which is written scientific information. Next is a fist-sized specimen of the mineral crocoite on limonite, a mass of smooth shiny and very delicate needles, mostly orange-red with a few white ones, each around 4 or 5 cm long.
