Johnson Farm.....
In February 2000, Sheldon Johnson
discovered numerous dinosaur tracks
preserved at the bottom of a 3-foot-
thick sandstone layer overlying a
mudstone layer on his farm within
the St. George city limits. As reported
in
Survey Notes,
v.
32, no. 3, because of
Johnson’s public-mindedness, scien-
tists from the Utah Geological Survey,
University of Utah, and University of
Colorado have been able to collect
significant data from this important
locality in the Whitmore Point Mem-
ber of the Moenave Formation. Ongo-
ing research has resulted in the identi-
fication of a number of different track
makers, fossil plants, invertebrates,
fossil fish, and beautifully preserved
sedimentary structures that record a
shallow, saline lake and its margin
during Early Jurassic time (about 200
million years ago) in southwestern
Utah.
