Dinosaurs, and other prehistoric creatures were trapped alive in tree sap in the abandoned mines in the Gravity Falls forest. The summer heat is causing the tree sap to melt, slowly releasing the dinosaurs and others from the sap.
History
At the end of the Gravity Falls Main Title Theme, the pterodactyl makes an appearance in a photograph.
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 go back to the past, they are attacked by a dinosaur.
In "Land Before Swine," the Pterodactyl escapes the tree sap and begins terrorizing the town 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.
