O is for...?

All of the O names in my Paleo Party! Are there any I'm missing? (I'm screaming, how do I have 10 O named critters and they're all facing the same way. This was 1000% not intentional)

Ordovician nautilid orthoceras

"Life in the Silurian Age: On the bottom are seen, proceeding from left to right, Corals (Stenopora and Beatricea) and a Gasteropod; Orthoceras; Coral (Patria); Crinoids, Lingulæ, and Cystideans; a Trilobite and Cyrtolites. In the water is a large Pterygotus, and under it a Trinucleus. Furthere on, are Cephalopods, a Heteropod, and Fishes. At the surface, Phyllograptus, Graptolithus, and Bellerophon. On the Land, Lepidodendron, Psilophyton, and Prototaxites."
