F110 is in area of WB00-31, larger shells are washing out of the unconsolidated silty sandstone. Source bed located and in situ fossils collected. In place fossils in slightly better condition than highly exfoliated float. Source bed is moist. See pic. 8. Lamb reports that F109, F110, F115, F116, and F119 are in same area at roughly the same elevation (– 25 ft).

Reported as F109, assigned by Hartman to F109a. I believe this F109 refers to WB00-31. Lamb reports that F109, F110, F115, F116, and F119 are in same area and same elevation (– 25 ft). Joe Beamon took me to a microlocality near where the new T. rex has been found (NW of Cold Turkey Coulee). At this site, shells are small, highly fragmented. They appear to be coming from a layer about 1.5 ft thick. Most of this layer is cemented sand. There is a possible secondary silty and less cohesive layer a few ft below. A few matrix specimens were collected.
