The skull of this Struthiomimus specimen is one of the best-preserved ornithomimid skulls known from Alberta. Like other ornithomimids (ostrich-mimic dinosaurs), this animal had long, powerful legs suited for rapid running to evade predators.

John Hunter (Ohio State University) is this week’s Speaker Series presenter. Join us April 18 at 11 a.m. in the Museum’s Auditorium for his talk, “Teeth and Mammalian Evolution.”

Merycoidodon gracilis was a small mammal distantly related to camels. This fully grown individual is roughlythe size of a house cat. Analysis of Merycoidodon teeth show that they were herbivorous, and likely browsed on plant shoots and leaves.

The Museum will offer special programming for Homeschool Day on Friday, May 17. Students can sign up for our programs, including Ancient Creatures, Cretaceous Crime Scene, and Fossil Casting. Learn more and sign up here: tyrrellmuseum.com/whats_on/speci…

The small aquatic reptile Keichousaurus is distantly related to plesiosaurs. Keichousaurus fossils like this specimen are found exclusively in China. This subadult male would have lived during the Triassic Period. #FossilFriday

Would you have a dinosaur pet if you could? Our Gallery Experience Officer Adin tried to convince “Trevor” the Albertosaurus to go for a walk outside for #NationalPetDay .

The tooth from today's #RTMPFossilChallenge belongs to Camarasaurus, the largest dinosaur on display in our Museum! These gentle giants fed on tough vegetation. Researchers estimate they could replace old teeth with new ones every 60 days. Art © James Kuether

For this week’s #RTMPFossilChallenge , can you name the animal this tooth once belonged to? This dinosaur lived during the Jurassic Period. A skeleton is on display in our Dinosaur Hall.

Join us for Jeff Liston’s presentation, “Descent into Carnivory: How Large Vertebrate Suspension-Feeding in the Mesozoic Ran Out of Options.” This free talk takes place on April 11 at 11 a.m. in the Museum’s Auditorium. Learn more: tyrrellmuseum.com/whats_on/speci…

Meet Shonisaurus sikanniensis, an ichthyosaur with its own room in the Museum. This specimen holds the world record for Largest Marine Reptile Skeleton. The skull lacks teeth, making this fossil the earliest-known example of a giant filter-feeding vertebrate.

This photo might look ancient, but it’s only a few decades old. The Triceratops skeleton being unloaded here is on display in our Dinosaur Hall. The Drumheller water tower is visible in the far background.

The first Styracosaurus was discovered in Alberta in 1913. These herbivorous ceratopsians (horned dinosaurs) lived during the Late Cretaceous. The name Styracosaurus means “spiked lizard,” referring to the many spikes on the skull’s frill. #FossilFriday

On April 27, help Drumheller break the world record for Largest Dinosaur Inflatable Gathering! Learn more: Travel Drumheller

After helping set a new world record, you can visit the Museum in costume, but please respect our non-costumed friends (and fossils). Guinness World Records

Plant, animal, or art? Pentacrinus subangularis is part of an extinct genus of crinoids that lived during the early Triassic Period. While they might resemble plants, specimens like these are actually marine animals. #RTMPCollections

Albertosaurus hatchlings grew quickly. Fossil evidence suggests Albertosaurus reached adulthood at about 18 years old, and continued to grow slowly for the remainder of its life, unlike mammals and birds that stop growing once they are adults.

This plesiosaur was excavated in extreme temperatures (-30 C)! Workers discovered large bone fragments while preparing the land for a new highway project in 2012. The skull wasn’t found, but our scientists believe the specimen belongs to the Wapuskanectes genus. #FossilFriday

This interactive display in our Cenozoic Gallery allows you—and some friends—to stand on the scale and find a creature that is equal to your weight. Have you met your match? #GalleryGlimpse
