Early mammalian recovery after the end-Cretaceous mass extinction: A high-resolution view from McGuire Creek area, Montana, USA. Geological Society of America Bulletin 130(11/12):2000-2014 [ER 4122]

Lithology: sandstone

Taphonomic context: fluvial deposit

Habitat comments: "Between the carbonaceous shale and the MCZ coal is the Z-Line channel deposit, containing both ZLQ and ZLE fossil localities, which are both near the base of the channel deposit and ~3 m below the MCZ coal but are ~12 m laterally apart from each other. The fossil-bearing horizon at ZLE is a ~12 cm thick, poorly sorted, brown to tan fine-grained sandstone that includes carbonaceous plant hash as well as vertebrate fossils. The fossil-bearing horizon at ZLQ is similar to that at ZLE"
the material is "isolated teeth and fragmentary jaws"

Life forms: ungulates,other small mammals

Sampling methods: screenwash

Sample size: 85 specimens

Years: 2014 - 2016

Museum: UCMP, RAM, UWBM

Sampling comments: the McGuire Creek localities were all revisited by UWBM crews led by Smith and Wilson in 2014, 2015, and 2016 after having been collected by UCMP and Raymond M. Alf Museum of Paleontology (RAM) crews led by Lofgren "in the 1980s and early 1990s"
