Discover the 16 Dinosaurs That Start With G

Dinosaurs are a spectacular part of the prehistoric past, and they continue to fascinate people the more we learn about them. There are so many species that it might seem impossible to know them all, but breaking it down by letter can simplify the process. Here are the dinosaurs that start with G: 

1. Gallimimus

This large theropod consumes an omnivorous diet and lived in the Late Cretaceous period 74-70 million years ago. It lived in Mongolia and could grow to almost 20 feet long and over 440 pounds. This dinosaur’s name means ‘chicken mimic’ in Greek. It got the name because it resembled a chicken, although it was much bigger.  

2. Gargoyleosaurus

A Gargoyleosaurus, or ‘gargoyle lizard’, is an armored dinosaur that can grow up to 13 feet long. It lived in the United States during the Late Jurassic period, 154-142 million years ago, and consumed an herbivorous diet.   

3. Garudimimus 

A Garudimimus, or ‘Garuda mimic’, is a large theropod, and it can grow to just over 15 feet long. It lived in Mongolia during the Late Cretaceous Period 99-89 million years ago. This dinosaur consumed an omnivorous diet.   

4. Gasosaurus

This small theropod, or ‘gas lizard,’ consumes a carnivorous diet and can grow up to 13 feet long. It lived in China during the Mid Jurassic period 170-160 million years ago.   

5. Gasparinisaura

This herbivorous dinosaur lived in Argentina during the Late Cretaceous period, or 86-71 million years ago. It’s a small ornithopod that only grows up to 2.5 pounds.

The Gasparinisaura dinosaur’s name means “Gasparini’s lizard’. Its name came from paleontologist and zoologist Zulma Nélida Brandoni de Gasparini, who discovered the fossils.   

6. Gastonia

Gastonia got its name from the word ‘Gaston’, as in Robert Gaston, who discovered the dinosaur fossils. It is an armored dinosaur that lived in the United States during the Early Cretaceous period 142-127 million years ago. This herbivorous dinosaur can grow up to 15 feet long.  

7. Giganotosaurus

This large theropod got its name from the words ‘giant southern lizard’ as it can grow up to 41 feet long and weigh 17,637 pounds. It prefers a carnivorous diet and has long, serrated teeth to slice other animals before eating them.   

The Giganotosaurus lived in Argentina during the Early Cretaceous period 112-90 million years ago. It is similar to a Tyrannosaurus rex but lived earlier and in a different location. This dinosaur also differs from a T-Rex by being taller, longer, and slimmer and having three fingers instead of two. 

8. Gilmoreosaurus

A Gilmoreosaurus is a large ornithopod whose name means ‘Gilmore’s lizard’, after the person that discovered it, Charles Whitney Gilmore. It is herbivorous and lived in China during the Late Cretaceous Period 76-70 million years ago. This dinosaur can grow up to 19 feet long.

9. Gorgosaurus

This carnivorous large theropod lived in the United States and Canada during the Late Cretaceous period, or 80-73 million years ago. It can grow to 28 feet long and got its name from the words ‘fierce lizard’.  

10. Gryposaurus

Gryposaurus means ‘hook-nosed lizard’, which describes the weirdly shaped nose assumed for this dinosaur. It is an herbivorous large ornithopod that can grow up to nearly 33 feet long. This dinosaur lived in the United States and Canada during the Late Cretaceous Period, or 86-71 million years ago.
