Tony's Bone Bed (DMNS 2182) (Cretaceous of the United States)

Also known as Tony's Bonebed

Where: Grand County, Utah (38.8° N, 109.5° W: paleocoordinates 39.1° N, 60.8° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Poison Strip Sandstone Member (Cedar Mountain Formation), Aptian (125.0 - 113.0 Ma)

• 3.75 m below top of member

•Ludvigson et al. 2010: U-Pb dates from near the base were approximately 119.4 +/- 2.6Ma

• bed-level stratigraphic resolution

Environment/lithology: lacustrine; gray limestone and lenticular, green mudstone

• "a meandering river complex" with lakes
• "medium- to corase-grained sandstone, and contains lenses of greenish mudstone...The bones occur in the interface between gray lacustrine limestone and overlying greenish mudstone. Evidence of pedogenesis (e.g., red-green mottling, calcareous nodules, possible rhizoliths) occurs in the upper part of the mudstone."

Size class: macrofossils

Collected by T. DiCroce in 1998; reposited in the DMNH
