Royal Tyrrell Museum of Palaeontology

The story of the Royal Tyrrell Museum begins with a chance discovery in the Alberta badlands. On August 12, 1884, Joseph Burr Tyrrell (pronounced TEER-uhl), while conducting a coal survey for the Geological Survey of Canada along the Red Deer River valley near present-day Drumheller, unearthed the partial skull of a large carnivorous dinosaur approximately 70 million years old. This specimen was formally described and named Albertosaurus sarcophagus (meaning 'flesh-eating lizard from Alberta') in 1905 by Henry Fairfield Osborn of the American Museum of Natural History. Tyrrell's discovery catalyzed decades of intensive fossil collecting in the region by institutions from around the world, establishing the Alberta badlands as one of the richest dinosaur fossil localities on Earth.

The idea for a dedicated palaeontology museum in Drumheller gained momentum through the late 20th century. After several years of planning and four years of active preparation, the Tyrrell Museum of Palaeontology opened its doors to the public on September 25, 1985. Originally conceived primarily as a scientific research facility, the plans were expanded to include extensive public galleries and display areas. In 1990, Queen Elizabeth II granted the museum the 'Royal' appellation, making it the Royal Tyrrell Museum of Palaeontology. Philip J. Currie, a leading Canadian palaeontologist, played a key role in the museum's founding and served as its first curator of dinosaurs before eventually moving to the University of Alberta.

The museum is situated in Midland Provincial Park, on North Dinosaur Trail, approximately 6 km (4 miles) northwest of the town of Drumheller in south-central Alberta. Drumheller lies within the Red Deer River valley, a landscape of deeply eroded sedimentary formations known as the Canadian Badlands. These badlands expose extensive outcrops of Late Cretaceous-age rock formations—principally the Dinosaur Park Formation, Horseshoe Canyon Formation, and related units—that have yielded some of the most abundant and diverse dinosaur fossil assemblages anywhere in the world. The museum is approximately 135 km (84 miles) northeast of Calgary and 280 km (174 miles) south of Edmonton.

The surrounding region, including Dinosaur Provincial Park (a UNESCO World Heritage Site located approximately 170 km southeast), has produced fossils of over 40 dinosaur species, along with numerous other vertebrate, invertebrate, and plant taxa spanning the Late Cretaceous. This geological and palaeontological richness has earned Drumheller the informal title of the 'Dinosaur Capital of the World.'

The museum's main building encompasses approximately 12,300 square metres (132,500 square feet), housing exhibition galleries, educational programming spaces, outreach facilities, a preparation laboratory, and a cafeteria and gift shop. The surrounding grounds extend over 77,500 square metres (835,000 square feet) of badlands terrain, including outdoor interpretive trails and a Cretaceous Garden featuring living relatives of Mesozoic plants.

As of 2020, the museum's collection comprised over 160,000 individually catalogued fossil specimens, of which more than 350 are holotypes—specimens that serve as the formal scientific basis for the description of a species. Approximately half of these items are fossils from the Cretaceous period, and roughly 85 percent of the Alberta-origin fossils were collected through the museum's own fieldwork. The collection grows by approximately 3,000 specimens per year, acquired through annual field expeditions conducted in the Alberta badlands, British Columbia, and the Canadian Arctic.

The museum's building has been expanded twice in the 21st century: a first expansion designed by BCW Architects was completed in 2003, and a second expansion followed subsequently.

The museum features a series of galleries and exhibit spaces that guide visitors through 3.9 billion years of life on Earth. Key permanent exhibitions include:

Dinosaur Hall: One of the world's largest displays of dinosaur skeletons, featuring species such as Tyrannosaurus rex, Triceratops, Camarasaurus, Stegosaurus, and numerous taxa from Alberta's Cretaceous formations, including Albertosaurus and various ceratopsians and hadrosaurs.

Cretaceous Alberta: A gallery focusing on the local Late Cretaceous ecosystem, showcasing the diversity of life in ancient Alberta, including dinosaurs, marine reptiles, and the flora that supported these ecosystems.

Burgess Shale Exhibit: Displays specimens and casts from the famous Burgess Shale Lagerstätte of British Columbia, illustrating the Cambrian Explosion—the rapid diversification of complex animal body plans approximately 508 million years ago.

Grounds for Discovery / Breakthroughs: An exhibit showcasing some of the museum's most significant and best-preserved fossil specimens, including Borealopelta markmitchelli—the world's best-preserved armoured dinosaur. For the museum's 40th anniversary in 2025, a new 'Breakthroughs' exhibit was unveiled, highlighting five transformative fossil discoveries including the first evidence of feathered theropods from Alberta.

First Life and Palaeozoic Era: Galleries exploring the earliest life on Earth and the evolution of marine and terrestrial ecosystems during the Palaeozoic.

Age of Mammals / Cenozoic: Exhibits documenting the rise of mammals following the end-Cretaceous extinction.

Preparation Lab: A glass-walled working laboratory where visitors can observe museum technicians preparing fossils—extracting, cleaning, and preserving specimens recovered from fieldwork.

Cretaceous Garden: An outdoor exhibit featuring living plants that are relatives of species that grew alongside the dinosaurs, providing a living reference for the ancient ecosystems of Alberta.

'Black Beauty' (TMP 1981.006.0001): A Tyrannosaurus rex skeleton discovered in 1980 by high school student Jeff Baker in the Crowsnest Pass region of southwestern Alberta. The specimen is distinctive for its dark, almost black coloration, caused by manganese minerals in the groundwater that permeated the bones during fossilization. 'Black Beauty' is one of the most complete T. rex specimens ever found and is among the museum's most iconic displays.

Borealopelta markmitchelli (TMP 2011.033.0001): Discovered in 2011 by workers at the Suncor Millennium Mine north of Fort McMurray, this approximately 110-million-year-old nodosaurid ankylosaur is widely recognized as the best-preserved armoured dinosaur in the world. The specimen retains three-dimensional body form with skin, keratinous sheaths over osteoderms, and organic residues in anatomical position across nearly the entire precaudal length. Museum technician Mark Mitchell spent over 7,000 hours preparing the specimen, and the species was named in his honour when formally described by Brown et al. in 2017. Analysis of preserved organic pigments revealed evidence of countershading—darker coloration on top and lighter underneath—suggesting this heavily armoured animal still relied on camouflage to avoid predators.

Albertosaurus sarcophagus: The museum holds multiple specimens of this Late Cretaceous tyrannosaurid, including material from a bonebed rediscovered in 1997 by Philip Currie, which provided evidence of possible pack-hunting behaviour in tyrannosaurs.

The Royal Tyrrell Museum functions as an active research institution with a staff of palaeontologists, preparators, and technicians. Research conducted at the museum covers vertebrate palaeontology, invertebrate palaeontology, palaeobotany, and taphonomy, with particular strengths in Late Cretaceous dinosaur systematics, ceratopsian and hadrosaurid diversity, tyrannosaur palaeobiology, and ankylosaur morphology. Museum scientists publish in peer-reviewed journals and collaborate with institutions worldwide.

The museum conducts annual fieldwork programs, including excavations in the Dinosaur Provincial Park area, the Horseshoe Canyon Formation near Drumheller, and increasingly in northern and Arctic regions of Canada. These field programs not only expand the collection but also provide the basis for public outreach programs, including dig-experience programs where members of the public can participate in supervised fossil excavation.

The museum offers a wide range of educational programs, including school group visits (nearly 30,000 students participated on-site in 2019), distance-learning programs (over 7,800 participants in 2019), guided tours, summer day camps, overnight sleepover programs, and field experience programs. A self-guided tour app is available with audio in English, French, Spanish, Chinese (Simplified), German, and Japanese.

The museum has been recognized as one of the world's top dinosaur museums by CNN, National Geographic, USA Today, and Smithsonian Magazine on multiple occasions. It is designated a Canadian Signature Experience by Destination Canada, reflecting its status as a nationally significant cultural attraction.

The museum generates the highest economic output of all Alberta Government heritage attractions. In 2019, it welcomed over 460,000 visitors from more than 150 countries. Cumulative attendance since opening has exceeded 13 million visitors. Admission is charged, with parking free. The museum is open seven days a week during summer (May 15–August 31) and closed on Mondays during the off-season.

Drumheller itself has embraced its palaeontological identity, with dinosaur-themed attractions throughout the town, including the 'World's Largest Dinosaur'—a 26-metre-tall T. rex sculpture with an observation deck inside its mouth, operated by the Drumheller Chamber of Commerce (scheduled to close at the end of 2029 due to lease expiration). The town's informal designation as the 'Dinosaur Capital of the World' reflects both the concentration of fossil resources in the surrounding badlands and the cultural prominence of the Royal Tyrrell Museum as a global destination for palaeontology enthusiasts.

The museum celebrated its 40th anniversary in September 2025. To mark the occasion, the museum unveiled 'Breakthroughs,' a new exhibit featuring five of its most scientifically significant fossil discoveries, and launched 10 pop-up exhibits at libraries across Alberta to bring palaeontology to communities throughout the province. The Borealopelta specimen was featured as a centerpiece of these travelling exhibits. These initiatives reflect the museum's ongoing commitment to both scientific excellence and broad public accessibility.
