À propos
SituĂ© dans la rĂ©gion du QuĂ©bec mĂ©ridional, sur la cĂŽte sud-ouest de la pĂ©ninsule gaspĂ©sienne, le parc national de Miguasha est un site palĂ©ontologique remarquable, considĂ©rĂ© comme la meilleure illustration de la pĂ©riode du dĂ©vonien ou « Ăąge des poissons ». DatĂ©e de 370 millions d'annĂ©es, la formation d'Escuminac, dĂ©vonien supĂ©rieur, renferme cinq des six groupes de poissons fossiles associĂ©s Ă cette pĂ©riode. L'importance de ce site tient au fait qu'on y trouve la plus grande concentration de spĂ©cimens fossiles de poissons Ă nageoires charnues â en Ă©tat exceptionnel de conservation â qui sont les ancĂȘtres des premiers vertĂ©brĂ©s terrestres respirant de l'air : les tĂ©trapodes.

Brief Synthesis Located in Canada, on the east coast of Quebec, Miguasha National Park protects and presents the Escuminac Formation, a rock formation with a rich fossil heritage recognized for the large number of exceptionally well-preserved fossil specimens it contains which are representative of the Devonian period. The fish, invertebrate and plant fossils at Miguasha bear witness to life as it existed on Earth 370 million years ago.Criterion (viii): Miguasha National Park is the most outstanding fossil site in the world from the standpoint of its representation of vertebrate life and its illustration of the Devonian period known as the Age of Fishes. The site is of paramount importance because it has the largest number and the best-preserved fossil specimens in the world of sarcopterygian fish, which gave rise to the first four-legged, air-breathing terrestrial vertebratesâthe tetrapods. Integrity Covering an area of 87.3 hectares, the park preserves the integrity of the fossil cliff and the Escuminac Formation. Protection of the beach area strengthens this integrity by permitting the recovery of fossils that fall from the cliff and are moved by the tides. With some 13,000 specimens, the parkâs national fossil collection also demonstrates the integrity of this scientific heritage. A large number of these fossils are exceptionally well preserved, with complete specimens, 3D specimens and fossilized soft tissues. The number of preserved specimens and their quality adds to the representativeness of the Devonian period and the uniqueness of the site. Protection and management requirements Protection of the integrity of this heritage is guaranteed by Miguashaâs conservation park status, established by the Quebec governmentâs Regulation respecting the establishment of parc national de Miguasha (1985) and by the provincial Parks Act (1978). As a member of the Quebec parks network, Miguasha National Park is the sole owner of the area that it is dedicated to protect and conserve. This legislative and institutional protection ensures the integrity of the site for the benefit of present and future generations. In 1990, the provincial mining act decree was issued to prohibit oil, gas and mineral exploration in a 775-hectare peripheral area surrounding the park. In 2004, the province changed the status of this buffer zone to a State Reserve, which means that no development can be undertaken there without the prior authorization of the Quebec Minister of Natural Resources and Wildlife. The park has adopted work tools to ensure effective and informed management of Miguashaâs paleontological and environmental heritage. These management tools provide a framework for paleontological research, enforcement of the Parks Act, field operations, excavations, laboratory and collection work, patrols, the parkâs education mission and its financial management. Over the longer term, special attention will be given to the monitoring of modifications and additions proposed to the property and its surroundings, particularly potential mineral exploration and mining activities; illegal extraction of fossils from the site; climate change; and erosion.
