Dinosaur Stampede National Monument at Lark Quarry Conservation Park (also known just as Lark Quarry or Dinosaur Stampede) in Australia is considered to be the site of the world’s only known record of a dinosaur stampede, with fossilised footprints are interpreted as a predator stalking and causing a stampede of around 150 two-legged dinosaurs.

This interpretation has been challenged in recent years, with evidence suggesting it may have been a natural river crossing. 

The fossils date to either the Albian or Turonian periods between 104 to 92 million years ago, and are part of the Winton Formation sandstone. In 2015, Winton Shire Council invited the Australian Age of Dinosaurs Museum of Natural History to take over the operation of public guided tours at Dinosaur Stampede National Monument. 

This joint initiative, implemented in April 2016, provides visitors with a broader understanding of unique Australian dinosaurs and the world they inhabited. In 2018 Dinosaur Stampede National Monument received 14,180 visitors. The Lark Quarry site is about 110 km (68 mi) south west of the western Queensland town of Winton.
