receptaculites
(REE-sep-TACK- you-light-eeze):

Referred to as the “sunflower coral” from 450 million years ago. At one time thought to be a sponge, it is commonly found as a flattened shape with a pattern of crossing lines like the head of a ripe sunflower. In more recent times,
Receptaculites
are considered spongelike rather than a true sponge.

crocodilians:

Crocodilians are the order of archosaurs (ruling lizards) that includes alligators, crocodiles, gavials, etc. They evolved during the late Triassic Period and are a type of reptile.

dragonflies:

Dragonflies, primitive flying insects that can hover in the air, evolved during the Mississippian Period, about 360 to 325 million years ago. Huge dragonflies with wingspans up to 70 centimetres (27.5 inches) existed during the Mesozoic Era (when the dinosaurs lived).
