Souvrství Cedar Mountain

Sedimentární výchozy souvrství Cedar Mountain.

Souvrství Cedar Mountain je geologickou formací na území východního Utahu v USA. Stáří sedimentů této formace má velké rozpětí 140 až 95 milionů let, jedná se tedy o usazeniny prakticky z celého období rané křídy (geologický stupeň berrias až cenoman).[1] Mocnost sedimentů činí místy až přes 1000 metrů, nejběžnější horninou je slepenec, pískovec a jílovec.[2]

Souvrství bylo poprvé definováno v roce 1944 geologem W. L. Stokesem.[3] Velmi početné fosilie dinosaurů byly ze sedimentů tohoto souvrství známé již dlouhou dobu, teprve od 90. let 20. století jsou však systematicky zkoumány paleontology.[4]
