When: Willwood Formation, Early/Lower Eocene (55.8 - 48.6 Ma)

• said to be both late Clarkforkian and Eocene

• group of beds-level stratigraphic resolution

Environment/lithology: wet floodplain; lithified, lenticular, brown wackestone

Collection methods: bulk, quarrying, chemical,

• "The entire lens J fauna [at SC-29] was recovered from a mass of freshwater limestone occupying a volume of approximately 2,000 c3 and weighing an estimated 5 kg" and vertebrates fossil were recovered by "dissolution of the limestone in dilute formic acid (10%)"
