Why did dinosaurs swallow rocks? - The Institute for Environmental . . .

This seemingly strange behavior has intrigued paleontologists for decades, leading to various theories and ongoing research
Gastroliths - ScienceDirect Gastroliths are trace fossils in need of ichnotaxonomy that provide important insights into various behaviors, notably diet, digestion, buoyancy control, and habitat preferences Reviews by Hendrik Klein and Robert Weems improved the clarity and content of the manuscript
Gastrolith | anatomy | Britannica …the food-pulverizing process, but such gastroliths, or “stomach-stones,” are only rarely found in association with dinosaur skeletons (A Seismosaurus specimen found with several hundred such stones is an important exception )
Palaeobiology: Solving the Riddle of the Gastroliths - OpenLearn Even palaeontologists disagree on the matter; some prefer the idea that they were used for ballast, others that they were used in digestion Future research may reveal new clues to help us solve this mystery, but for now it remains the ‘riddle of the gastroliths’
