AMBER ASSOCIATED WITH LATE CRETACEOUS DINOSAUR BONEBEDS IN WESTERN CANADA.
MCKELLAR, Ryan C., ENGEL, Michael S., TAPPERT, Ralf, WOLFE, Alexander
P., TAPPERT, Michelle C., and MUEHLENBACHS, Karlis.

The first report of inclusion-bearing amber in direct association with
a dinosaur bonebed was made in 2004. Subsequently, a range of fossil
deposits within the Late Cretaceous strata of Alberta and Saskatchewan
have been found to contain at least trace amounts of amber.
Improvements in processing techniques have allowed us to examine many
of these ambers for inclusions, in addition to conducting bulk
chemical analyses (Fourier-transform Infrared spectroscopy) to
establish source tree identity, and stable isotope analyses (of C and
H) to investigate both ecological conditions and events within the
paleo-forest. Here we will discuss preliminary findings from the Danek
Bonebed near Edmonton, Alberta (Horseshoe Canyon Formation,
Maastrichtian); Dinosaur Provincial Park, Alberta (Dinosaur Park
Formation, Campanian); Pipestone Creek Pachyrhinosaurus Bonebed near
Grande Prairie, Alberta (Wapiti Formation, Campanian); and the
‘Scotty’ Tyrannosaurus rex Bonebed near Eastend, Saskatchewan
(Frenchman Formation, Maastrichtian). These case studies illustrate
the range of paleoecological and taphonomic data that can be obtained
from truly contemporaneous amber deposits and the potential for future
research. In addition to aiding in correlation, many of the
characteristics examined provide insights into specific events during
the time of bonebed formation, such as infestations, and background
conditions, such as surrounding water sources or paleotemperature.
Amber may even provide a proxy for oxygen levels in the ancient
atmosphere.
