We had a great first fossil sorting session of 2026! Some really incredibly preserved teeth and fish bits this time. albertapaleo.org/events/fossi... #fossils #alberta #microfossils

An insectivore premolar, found by Georgia Hoffman. There are two thin roots coming out of the bottom of the tooth, and on the top are roughly six very clearly defined cusps. It's a somewhat scary looking tooth!

A picture of an insectivore premolar, found by Vaclav Marsovsky. There are two broad roots coming from the bottom, and on the top the tooth is roughly triangular with clearly-defined cusps.

A fish centrum (circular part of the vertebra), found by Rex. This one is seen face-on, but even so it's clear that the centre of the centrum is quite concave. Around the outside are several bumps which would probably mean a lot to someone better versed in fish anatomy, but are opaque to me!

A fish fin ray spine, found by Jess. The main part of the fossil is a shaft of bone sticking straight up; this is the spiny part of the spine. The base is a small flange of bone which would be anchored in the fish's body.

This Fossil Friday features a dicot leaf from Calgary’s Paskapoo Formation (~50 million years old). This sandstone is common around the city and often contains plant and bivalve fossils, so keep your eye out! #fossilfriday #palaeontology #paleontology #fossils #alberta #plants #yyc

A fossilized leaf impression in brown sandstone. The leaf itself is quite broad and the veins are clearly visible. It looks very similar to the leaf of an aspen or elm. Around many of the basal veins the colour is a much darker brown.

This week's fossil is a Composita brachiopod from the Carboniferous Banff Formation in Kananaskis! The concentric circles (beekite) occur when the soft calcite / aragonite of the shell is replaced with more resistant silicate minerals. #fossilfriday #palaeontology #fossils #brachiopods #alberta

Composita brachiopod. The shells look like spheres just emerging from the grey matrix which surrounds them. There are folds / valleys in all of the fossils. Visible on the surface are concentric rings. To the top left is a portion of a pocket knife, showing that the fossil is just a few centimetres across.

A very accessible fossil! This bivalve (right) and gastropod shell impression (left) were in Glenbow Ranch Provincial Park, just outside of Cochrane, AB. These are from right after the extinction of most of the dinosaurs (Paskapoo Formation, early Palaeocene). #fossilfriday #palaeontology

A piece of sandstone. Rock is tan brownish, with a pitted surface. In the middle is a red pocketknife. To the left and below it is a spiral impression in the surface; the shell of a gastropod (snail relative). To the right is a fossil bivalve, looking just like a clamshell you might find on the beach today.

Another great fossil sorting session this Sunday! It was an unusually fishy afternoon with lots of centra, scales, teeth, and fin rays being found. Next session: Nov. 23 at MRU in Calgary. albertapaleo.org/events/fossi... #palaeontology #paleontology #fossils #microfossils #eocene

A fish centrum through a microscope. There are many different pebbles in the field of view. The centrum (backbone) itself is in the centre of the field of view and is a light brown in colour. It looks almost like a brown satellite dish. The end of the vertebra is circular and concave inwards, with rings being clearly visible. Around the side of the vertebra are small protrusions sticking out.

A ray tooth plate, found by Gerhard Maier. It's an unusual structure. Roughly rectangular, there are six bands of harder enamel running parallel to the shorter side of the rectangle. When the ray was living these would have been packed together to provide a crushing surface.

A picture of an insectivore premolar, found by Labib Chowdhury. The tooth is on the white background of a slide and has a dark-brown enamel top and a lighter dentine root. There are two visible roots. The darker enamel portions are split into three high peaks.

An image of a lagomorph incisor found by Vaclav Marsovsky through a microscope. There are a few bits of sand in the view, but not too many. The incisors are quite distinctive, being curved with a black enamel surface. There is a trough in the middle that makes it look like this is really two teeth stuck together.

The calcaneum (ankle bone) of a rodent from the Eocence Cypress Hills formation was found by one of our volunteers during a fossil sorting session! albertapaleo.org/events/fossi... for info + sign up. #palaeontology #paleontology #fossilfriday #fossil #eocene #rodent #saskatchewan #alberta

There are several parts to this image.

In the top left we see a picture of a tray of matrix (dirt) being viewed under a microscope. A circle is cut out and magnified to the right, where we can see the fossil, the ankle bone (calcaneum) of a rodent. This is the view through the microscope and so the fossil is surrounded by bits of dirt and is very difficult to see. Below that is another view through the microscope where the dirt has been cleared away and only the fossil is left. On the left is a skeletal image of a rat with the ankle bone highlighted in red.

The fossil itself is somewhat long and stick-like, with a protuberance on the end where the tendons would connect to. It's very small and brown.

A new tyrannosaur from Mongolia - Khankhuuluu mongoliensis, the 'dragon prince of Mongolia' - changes how we understand tyrannosaur evolution! Changes in development and movement from NA to Asia and back! 🔗 www.nature.com/articles/s41... #palaeontology #fossils #dinosaurs #tyrannosaur #alberta

A picture of the first page of the paper. It's largely just text.

An illustration of how changes in developmental timing can affect species. At the top are the skeletals of three dinosaurs: Khankhuuluu and then a juvenile and adult Gorgosaurus. It's clear from the illustration that the skull of Khankhuuluu looks somewhat slender and light, like the juvenile Gorgosaurus.

There's also a cutout / magnification of Khankhuuluu's skull above the skulls of Alioramus and Tyrannosaurus. Again, it's clear that the skull of Khankhuuluu resembles that of Alioramus (the more 'juvenile' looking one) and less like Tyrannosaurus (the more 'adult' one).

An image of the biogeography of the tyrannosaurs.

At the bottom is a scale of the geological time periods, showing when the different species lives.

Going across the page is a phylogeny of the tyrannosaurs. Toward the right Khankhuuluu is highlighted, just outside of Eutyrannosauria. You can also see the position of Albertosaurus (early-branching member of Eutyrannosauria) and right at the end, Tyrannosaurus rex.

Toward the left is a globe showing North America and Asia. There are arrows showing that tyrannosaurs moved from Asia -> NA and then back again.

An image of Khankhuuluu by Julius Csotonyi. It's a medium sized theropod. In the image it's standing with its head cocked down. It's covered in brownish / red fine fur or scales and the tip of the snout and a ridge above the eyes are blue.

New paper from U of A's @chrissygarros.bsky.social and team: ordinary troodon foot bones turn out to tell an extraordinary story! Careful study revealed injuries, growth patterns, and three(~) distinct growth trajectories. onlinelibrary.wiley.com/doi/10.1111/... #palaeontology #fossils #dinosaurs

An image of the first page of this paper; it's largely just text.

A complicated image. The background is a map of Alberta, showing the relative position of Dinosaur Provincial Park with respect to Calgary and Edmonton (east and slightly south of Calgary; east and quote south of Edmonton). In the bottom right is a skeletal of a troodon (a small theropod dinosaur) with the metatarsals (lower foot bones) highlighted in red. In the top right is a blown up image of the lower leg / foot, again with the metatarsals highlighted in red. To the right of that are images of cross sections of the bones showing distinctive growth lines.

Another composite image. In the middle is a large image of two metatarsal bones with a plane through them showing where the bones were cut. Surrounding that are several different images of the cross sections, again showing growth lines and other elements of the histology.

Finally, some graphs!

On the left are two line graphs, both showing a roughly linear trend. These come from one set of metatarsals.

On the bottom is another set of line graphs. In this one there are two main lines, plus a shorter one that can be ignored. Both of the lines show a sigmoidal (s-shaped) curve, with one substantially above the other. This indicates roughly the same trajectory, but with one individual achieving a much larger size than the other.

The difference in the sigmoidal curves is probably due to injury. The difference between the linear growth and the sigmoidal one is unclear - it could be species differences, sex differences, population differences, or something else entirely!

A hadrosaur fossil turned hoodoo! In the Horseshoe Canyon Formation, erosion (up to 4 mm/year) leaves tougher fossils standing tall as the softer rock wears away. #FossilFriday #palaeontology #hadrosaur #dinosaur #alberta

A close-up shot of a hoodoo formed from a hadrosaur bone. The fossil is sitting on a pedestal of softer stone. There's a pocket knife next to it for scale.

#whalewednesday The spectacular early toothed whale Xenorophus sloanii from the Oligocene (~28 mya) of South Carolina! This is a critical transitional fossil, known from about a dozen skulls and partial skeletons. Read more about Xenorophus here on my blog: coastalpaleo.blogspot.com/2024/03/the-...

A black and white skeletal reconstruction of Xenorophus sloanii, and a pair of photos of the skull and neck vertebrae of the best known specimen in top and side view.

An analysis of 1.4 million online images published in Nature suggests that women are represented as younger than men across occupations and social roles. These stereotypes may be further reinforced by mainstream algorithms. go.nature.com/4o9zHWw 🧪

This is figure 3, which shows Googling for images of occupations amplifies age-based gender inequality in people’s beliefs.

I love shitting on social media as much as the next guy, but Skype a Scientist was built directly from social media connections. We've matched over 60,000 classrooms with scientists from it... That's pretty great.

Two events at the RAM. Sat, Oct 11: Learn about the ice-age horses that use to live here. Sun, Oct 12: Learn about how palaeontologists can use dinosaur teeth to learn more about them. royalalbertamuseum.ca/whats-on. #palaeontology #paleontology #fossils #dinosaurs #iceage #horse #alberta

A poster containing the same information as the post. To the right is the text, and to the left is an image of a horse skeleton. A presenter is motioning to the skull.

A poster describing the same information as in the post. The text is to the left and to the right is an image of a theropod skull with a large toothbrush being held behind it.

Excavated from the Pisces Point locality of Scollard Formation in Alberta, Canada, ~67 million years old, Acronichthys maccognoi, newly reported in @science.org, was recovered from ancient water body that flipped seasonally between fast-flowing channels and quiet, still pools.

This #FossilFriday, we have our museum's most recognizable fossil: Fish-Within-A-Fish! Featuring Xiphactinus, a large predatory fish, with the smaller Gillicus in its gut contents. It was found and collected by George F. Sternberg in 1952, and is now an iconic part of the Sternberg's collections!

Did you know that mastodons used to live in Alberta? This jaw was found in Edmonton and is currently housed at the Royal Alberta Museum. Mastodon are relatives of elephants and have very distinctive jaws and teeth. #fossilfriday #palaeontology #paleontology #mastodon #fossils #mammals #alberta

Two lower jaws of a mastodon in a museum display. The teeth have very high cusps. In the corner is a skeletal of a mastodon next to a person, showing that the person roughly comes up to the mastodon's shoulder.
