Grazie ad una serie di impronte ritrovate in Alaska, i ricercatori del Perot Museum of Nature and Science di Dallas, in Texas, hanno scoperto che gli adrosauri – una famiglia di dinosauri di grandi dimensioni e con un becco d'anatra – amavano gli habitat influenzati dalle maree.
Nella ricerca sono state documentate diverse impronte di animali nell'area di Aniakchak, a circa 670 km a sud-ovest di Anchorage, la più popolosa città dello Stato.
Le nuove tracce scoperte dai ricercatori risalgono al tardo Cretaceo, quindi a circa 66 milioni di anni fa, e fanno parte di lavori di scavo e di studio condotti tra il 2001 e il 2002 e tra il 2016 e il 2018. Sono stati identificati più di 75 sentieri fossili, con decine di impronte di dinosauri.
