Palaeontologists who flocked to Alberta's badlands around the turn of the last
century in search of dinosaur fossils rarely marked the location of
their finds for future generations.
That mystifies Darien Tanke, a technician with the dinosaur research
program at the Royal Tyrrell Museum near Drumheller.
"In their field notes, they might say a specimen was found five to 10
miles upstream from a certain community," Tanke says. "That's like
saying, go find the office desk that's eight miles down the street from
you."
Likewise, he says, "We might find a gaping hole in the side of a hill but not
know what came out of it. The badlands are a complex topography and
they have high erosion rates. So it's hard to say what came out of
what hole."
Tanke has begun a "mystery quarries" project to locate and mark all the fossil
quarries in Dinosaur Provincial Park and to match specimens with the
quarries they came from.
"Certain types of dinosaurs are only found in certain layers. We need to see
where various specimens are found in relation to each other to
understand how they evolved. Also, sometimes you can go back and
find pieces they (early paleontologists) left behind."
In September 1999, Tanke issued a call for people whose families lived in
the Brooks area during the Dinosaur Rush to bring in photos taken
between 1913 and 1956 that might help locate quarries in the park.
"A lot of the public used to come out to what is now
Dinosaur
Provincial Park on Sunday picnics. They would meet the
palaeontologists and invite them for lunch. Then the
palaeontologists
would take them out to digs. We assume some people would have had
cameras with them and that there would be pictures they took hidden
away in old shoe boxes."
Tanke's appeal has garnered "a few nibbles, but not quite the response we
were wanting," he reports. By coincidence, a woman visiting from
Denver has recently brought in three photo albums dating to 1921. Her
father, then a student at the University of Alberta, had served as a
field assistant for George Sternberg, a well-known palaeontologist.
"He had photographed four different quarries, some of them with
specimens still sitting in the ground," Tanke says. "We were able to
compare rocks in the pictures with sites in the park. Things started
falling into place." Tanke combines clues in photos with
palaeontologist's field notes and objects found at quarries in the
park to solve the riddle of who dug up what from where.
The museum has marked close to 250 quarries and Tanke estimates as many
more remain to be found.
The "mystery quarries" project has attracted the interest of several
individuals and companies. Bill Spencer, manager of business
development for natural gas liquids with BP Amoco Canada, has
contributed cash and equipment to the project. He had been involved
in the Field Experience Program with the museum and his family has
been active in historic preservation.
"This quarry thing was a natural fit for me—history and dinosaurs," he
explains. Spencer enlisted the help of Rob Prayer and Paul Cardiff
of Calgary-based Ellipse Spatial Services and last summer they
conducted a GPS (Global positioning system) survey of the park.
BP Amoco and Novatel provided the use of a digital camera and
state-of-the-art equipment for the project. The result is an aerial
map with GPS coordinates for each quarry found.
The team mapped about 60 quarries last summer and intends to return to
the project this year.
