They one shot then and give extra resources from harvesting with a salamander. You won't need oxygen as you can breathe from its air sac. Yeah ichtyosaur would be fine, and you will definately want some points in oxygen depending how deep you need to go for them.Trilobites comprise a complex and huge clade of arthropods with estimates of number of species exceeding 15,000. The extinct trilobite represents a problem for classification, a problem unlikely to benefit from modern genomic science. Darwin was confident in his conjecture that trilobites descended from one Pre-Cambrian crustacean ancestor.

This exceptional fossilThe trilobite body is divided into three sections: a head, thorax, and tail. In the earliest trilobites, the tail is very short and vaguely pronounced. Trilobites had antennae, and some had horns that resemble those seen on modern beetles. Trilobites filled a variety of ecological niches, and included predators, scavengers or filter feeders.Ordovician Period.
