As every who has followed this thread know, David Loope and others in
GEOLOGY (Jan 1998) suggested that the dinosaurs were trapped in local
landslides of sand hills. The suggestion was made that this might be a
subaqueous catastrophe. Caliche layers found in the Djakokhta Fm. argues
against that interpretation. Arthropod burrows found in the Djakokhta
formation argue that the deposit was not formed rapidly and catastrophically.
Anyone wishing to include these dinosaur beds in the Noachian global flood
must deal with the following facts. The caliche beds form several layers in
the dunes (see D.A. Eberth, "Depositional Environments and Facies
transitions of Dinosaur-bearing Upper Cretaceous Redbeds at Bayan mandahu
(Inner Mongolia, People's Republic of China) Can. J. Earth Sci. 30(1993)
p2205; and ~David E. Fastovsky et al, "The Paleoenvironments of
Tugrikin-Shireh (Gobi Desert, Mongolia) and Aspects of the Taphonomy and
Paleoecology of Protoceratops (Dinosauria: Ornithischichia)", Palaios,
12(1997):59-70)
These caliche beds require evaporation to form and also require some time.
Then the caliche beds were burrowed through by arthopod burrows.
"In contrast, the burrows that cut the sheet-like calcareous
concretions of facies E-2 clearly postdate the onset of carbonate
accumulation. The crosscutting burrows, the location of concretions within
sediments deposited high on the slopes of large bedforms (far above the
water table), and the find grain size of the calcite indicate that
concretion development startedwithin the vadose zone."~David B. Loope, et
al, "Life and death in a Late Cretaceous Dune Field, Nemegt Basin,
Mongolia," Geology, 26(1998):1:27-30, p. 28-29
must be dug through it.
Secondly, there is evidence of elapsed time in the relationship of the
burrows to the fossil dinosaurs. The burrows dig through the bones.
"The articulation of so many skeletons suggests to us that there was
little post-death dismemberment by scavenging or by sedimentary processes. It
is clear that an abundant arthropod fauna subsisted at Tugrik, and compelling
evidence of arthropod scavenging of Protoceratops comes from the observation
that Type III burrows have been found penetrating bone surfaces."~David E.
Fastovsky et al, "The Paleoenvironments of Tugrikin-Shireh
(Gobi Desert, Mongolia) and Aspects of the Taphonomy and Paleoecology of
Protoceratops (Dinosauria: Ornithischichia)", Palaios, 12(1997):59-70, p. 66
I would submit that the Djakokhta formation could not be part of the global
flood.
