1980 P. Dodson et al. in Paleobiology 6 229/1 We believe that trampling by large dinosaurs (‘dinoturbation’) may have had an impact on both the sediments and remains of the small biota.
1986 Nature 19 June 732/3 A brontosaur trampled across a collection of living unionid clams in shallow water and preserved them for posterity in the base of the huge footprints, a sedimentological phenomenon termed dinoturbation.
2017 D. Norman Dinosaurs: Very Short Introd. (ed. 2) vi. 123 Dinoturbation might be just a sedimentary phenomenon, but it hints at another biological impact of dinosaur activity that might eventually prove to be measurable over time.
