Aeger Elegans is a species of shrimp that was found in the Solnhofen limestone of Germany.  Point Value: 1 Ptero Tidbit: Pterosaurs all had the same basic body plan, but different species could vary dramatically.

These coniferous trees lived all over the globe during the Jurassic and Cretaceous periods. Point Value: 1 Ptero Tidbit: In the Jurassic Period a new group of pterosaurs emerged. They had shorter tails, longer hands and neck bones, and bony crests on top of their heads.

In Morocco, scientists found the tracks of a theropod (a type of carnivorous dinosaur) among those of pterosaurs. Did dinosaurs pose a threat to pterosaurs? Evidence is scarce, but some fossils suggest they did. PLAY on one pterosaur to remove it from the game and leave this card in its place.

The long spine attached to the dorsal fin of the Ischyodus may have even been venomous. Point Value: 2 Ptero Tidbit: No one knows exactly what pterosaurs looked like. The pterosaur colors and patterns on these cards are borrowed from animals living today that had similar lifestyles.

A meteorite has crashed, disrupting the entire ecosystem! PLAY on any level 1 or 2 card. EFFECT: Destroy the selected card and each card lower than it on its food chain. Discard this card.

The climate has shifted. PLAY on any level 1 or 2 card. EFFECT: Leave this effect card on the table and permanently change the terrain of the card underneath to land, sea or ocean. (Remove at end of game so opponent can collect the points underneath.)

A volcano has erupted, wiping out larger reptiles in this land or water area. PLAY on any level 1 or 2 card. EFFECT: Destroy the selected card, discard this one, and freeze movement for all adjacent cards for one round (only horizontal and vertical).

PLAY this card on another player’s turn when they use an event card against you. EFFECT: Stop the effect of their event card and discard this card.

Cockroaches existed before pterosaurs and dinosaurs. The first fossils of modern cockroaches appeared in the Early Cretaceous period. Point Value: 2 Ptero Tidbit: When scientists find a small pterosaur they try to determine whether it was a juvenile or an adult member of a small species of pterosaur.
