Late Jurassic
145 - 163.5 Ma



ID: 2180642
Brushy Basin Member of Morrison Formation

Age: Jurassic (145 - 163.5 Ma)

Stratigraphic Name: Brushy Basin Member

Description: Variegated siltstone, mudstone, smectitic clay, and lesser amounts of calcareous sandstone and conglomerate, locally with thin lentils of dense limestone; siltstone and mudstone are principally maroon, light purple, grayish red, and light to medium gray; crops out as gentle slopes and steep rounded hills, locally in steep slopes with slight ledges; sandstones range from poorly sorted, conglomeratic, and coarse-grained to well sorted, very fine grained to silty; locally has lenticular conglomeratic sandstone at base with bright-colored chert pebbles and cobbles; lower contact is generally a poorly exposed transition zone of frothy-weathering variegated mudstone and thin light-brown sandstone between the basal conglomeratic sandstone of the Brushy Basin Member and the uppermost sandstone lens of the Salt Wash Member; locally contains petrified dinosaur bone and wood; 76 to150 meters (250-500 ft) thick; Upper Jurassic.
