In 1967 Shiva Balak Misra, a
graduate student at Memorial University of Newfoundland, and his field
assistant Paul Thompson, made an extraordinary discovery at Mistaken
Point, a rocky headland jutting into the Atlantic Ocean. The place is
so named because on several terrible occasions ships travelling east
from continental North America to St. John’s or ports north,
mistook the Point for Cape Race, turned northwards and wrecked on the
rocks. Today the place is world famous for its abundant, diverse and
well-preserved fossil assemblages—the oldest fossils of complex
life forms found anywhere on
earth.
579 to 542 million years ago
(over 300 million years before the dinosaurs) a chain of volcanoes
spewed ash that sank into deep water and settled soft-bodied sea
creatures living upon the ocean floor. The ash killed these
organisms and then preserved impressions of them as it was
buried by additional layers of sediment. Eons later, a combination
of tectonic uplift, Pleistocene glaciations and marine erosion has
resulted in the exposure of these fossils. Known to scientists as
the Ediacara Biota (Edi-ak-ara-By-oh-ta), they are named for the
Ediacara Hills in South Australia, where the first large examples were
discovered in 1946. These ashes can also
be radiometrically dated—by
precisely measuring the ratio of uranium and its decay
product lead contained by individual tiny crystals of zircon
found within an ash, its age can be accurately determined.
In 1987, a 9-kilometer stretch
of coastline at Mistaken Point was established as Mistaken Point Ecological
Reserve under the management of the Government of Newfoundland and
Labrador.
In 2003, following the discovery of more fossils along the coast
northwest of Mistaken Point, an emergency extension was added to the
original protected area. On March 17, 2009, this extension became
a permanent part of the reserve. Since 2004, in recognition of the
global significance of its fossil resources, Mistaken Point Ecological
Reserve has been on Canada's official Tentative List of potential
World Heritage properties. Work has begun on the Reserve's forthcoming
application for full UNESCO World Heritage Site status.
Public access to Mistaken Point Ecological Reserve's globally
significant fossil-bearing surfaces is
by official guided tour ONLY.
Visitors are reminded that the
collection or attempted collection of fossils or rock specimens
in the Reserve is strictly prohibited.
To enhance fossil protection and public safety and reduce cliff-top
erosion, two-thirds of the Reserve's coastline is designated as a
Fossil Protection Zone. Entry to the Fossil Protection
Zone—which extends 15 metres inland from the cliff/turf
edge—is by permit or guided tour
ONLY. Please note that dogs cannot be included on tours to the
fossil sites.
The Province's Parks and
Natural Areas Division operates at least one free guided tour from
Mistaken Point each day from late May to early October. These tours,
which leave from the Edge of Avalon Interpretive Centre, last
approximately 3.5 hours and include a 45 minute walk (one way) to the
fossil site. For more information about these tours, call the
Interpretive Centre at Portugal Cove South (709-438-1100) and ask
to speak to one of the Reserve's Interpreters. For Mistaken Point
Ecological Reserve permit requirements with respect to scientific
research, educational tour groups, commercial operators or the
