Gallic Epoch it was the middle part of the Cretaceous Period about 127 million to 89 million years back.

Gallimimus it was an ostrich-like dinosaur about 17 feet long. This lightly-built, fast-running theropod was a long-beaked omnivore (eating plants and animals) from the late Cretaceous era, about 75-70 million years ago.

Ganglion is a accumulation of nerve tissue exterior the central nervous system (in any animal). Some of the larger dinosaurs (some sauropods and Stegosaurus) may have a ganglion at the bottom of the tail.

Gargoyleosaurus it was an unbreakable dinosaur that lived throughout the late Jurassic era, about 154 to 144 million years ago.

Garudimimus it was a theropod dinosaur that lived throughout the late Cretaceous era, about 89-83 million years ago.

Gasosaurus it was a theropod dinosaur from the mid Jurassic era, about 175-163 million years back

Gastonia was a deeply armored plant-eating dinosaur from the early Cretaceous period.

Gastralia it is also called gastric ribs, abdominal ribs, or belly ribs are hanging ribs in the belly area.

Gastroliths are stones that some animals ingest and use to help grind up rough plant matter in their digestive system.
