Dinosaurs
Dinosaurs, among other prehistoric creatures such as pterodactyls, were trapped alive in tree sap in the abandoned mines under the Gravity Falls Forest. The summer heat is causing the tree sap to melt, slowly releasing the dinosaurs and others from their preserved states.
History[]
At the end of the Gravity Falls Main Title Theme, the pterodactyl makes an appearance in a photograph.
Season 1[]
In "The Time Traveler's Pig," when Blendin Blandin's wrist-worn device malfunctions, a scene from "Land Before Swine" with dinosaurs trapped in tree sap is shown on his jacket. Later, when Dipper and Mabel Pines go back to the past, they are attacked by an Allosaurus.
In "Land Before Swine," the pterodactyl escapes from the tree sap and begins terrorizing Gravity Falls and ends up stealing Waddles. It retreats to the abandoned mines, where other dinosaurs are seen trying to escape. It also had an egg which hatched into a baby pterodactyl that ate Old Man McGucket. In the end, the pterodactyl and dinosaurs were trapped in the abandoned mines.
According to Gravity Falls: Journal 3, Grunkle Stan stole a Compsognathus egg from the mines in order the use it for an attraction. The Compsognathus that hatched was named "Compy" and started picking tourists' pockets before it was captured by the Mystery Crew. Compy was then relocated to Farmer Sprott's farm.
Season 2[]
Mabel gave Dipper a dinosaur sticker saying "Ext-Roar-Dinary" in "The Golf War."
In the episode "Soos and the Real Girl," a dinosaur poster can be seen in Soos' room.
In "Society of the Blind Eye," a skeleton of a Protoceratops is on display in the Gravity Falls Museum of History.
In "Weirdmageddon Part 1," the pterodactyl is seen again, on top of Gravity Malls.
In "Weirdmageddon 3: Take Back The Falls," the Tyrannosaurus is attached to the Shacktron's left arm, its head and arms freed to use as a weapon against Bill Cipher and his gang. The Tyrannosaurus succeeds in ripping out Bill's eye while in combat with him, temporarily disabling the demon and allowing the rescue team to parachute past him to the Fearamid, but is prevented from fighting Bill further once he gains the upper hand.
Appearance[]

- Tyrannosaurus rex
- Stegosaurus
- Gallimimus
- Utahraptor
- Triceratops
- Brachiosaurus
