#TrilobiteTuesday
Here is the cephalon (head) portion of an Olenellus trilobite from the Lower Cambrian Rome shale collected in Shelby County, Alabama. Early cambrian rocks in the Southeast are poorly exposed but and hard to find fossils in. These are some of the earliest trilobites in N. America.
New Stigall Lab paper! Noel Hernandez Gomez analyzed niche stability across the Richmondian Invasion in Nashville, TN using PaleoENM--and found that Nashville and Cincinnati faunas responded differently to the same invasion event. Super interesting! authors.elsevier.com/a/1miJF_j8pCF4
Launching this month, Curator Conversations is a new speaker series bringing you face-to-face with the experts who uncover the stories of our province—and beyond.

#FossilFriday A beautiful Cretaceous seastar. This fully articulated specimen of Calliderma was collected in the Chalk of England.
Our work on the histology and mineralization patterns of 3 Devonian chondrichthyan taxa from Morocco is finally out now! I am very happy to share this work and hope there will be more to come about early shark tooth histology!
Thanks to all my co-authors, especially Hector Botella!

It's Trilobite Tuesday! Some trilobite fossils provide extra insight about life in the Paleozoic seas—like this 430-million-year-old Arctinurus from the Rochester Shale of New York! Its 5-in- (12.7-cm-) long body is covered in brachiopod shells that hitched a ride on the trilobite's carapace.
Great start to the ISELV conference in Berrechid, Morocco. Has been fascinating to learn more about the latest work on early vertebrates. Looking forward to visiting some amazing Paleozoic sites in the coming days!
Welcome back to #fossilfriday!
Here are the impressions of the Inoceramid clam Mytiloides mytiloides. This specimen comes from the Late Cretaceous (Cenomanian-Turonian) Greenhorn Formation (Colorado Group) in northwestern Nebraska.
🚨New paper🚨
A new article in Swiss Journal of Palaeontology, led by Dr. Lorenzo Lustri (Yunnan University), in which we discuss the affinities of two enigmatic Ordovician arthropods from the Czech Republic by means of elliptical Fourier analysis.

Manitoba Museum does the BEST dioramas, and this is no exception. totally recommend a visit!
Putting the finishing touches on the @romtoronto.bsky.social shark workshop! Tomorrow we'll be diving into shark evolution and diversity, from the earliest jawed fish, to Megalodon and the mako. #FossilFriday
ISELV pre-conference field trip has started strong, led by our fantastic host Abdul Lagnaoui! Day 1 & 2 spent in the #Cretaceous and #Jurassic of #Morocco 🇲🇦 🦖 🦕 heading back in time to Permian and Carboniferous next … #palaeontology #ISELV2026
entire skeleton of a fossil amphibian
It’s extremely rare to find an entire skeleton of a fossil amphibian. But that’s what this is – except for a few missing pieces of the hands and feet and the very tip of the tail.
leaf shaped fossils of Charnia brasieri and Trepassia sp.

Happy #FossilFriday how does a thread about the Inner Meadow biota and unexpected age for the fossils, and a refocusing of Martin Brasier’s #KotlinCrisis sound?
We’ve been trickling out our findings from Inner Meadow including #Charnia brasieri, #Aninoides and there's even cooler stuff in review. 🧵
A glass topped museum display case containing a variety of fossil specimens along with specimen models, informative text panels, and photographs.
Last year, Dr. Moysiuk and Royal Ontario Museum colleague Dr. Caron announced their discovery of a 506-million-year-old predator, Mosura fentoni.
See fossils and 2D & 3D representations of Mosura fentoni and related species in new exhibit “Weird Wonders from the dawn of complex life”! #FossilFriday
Detail of the wood tissue in a fossil stem of Sigillaria seen under the microscope. It shows files of conducting cells and rays.
Today's lycopsids ("clubmosses") are small plants and do not produce wood but some of their Paleozoic relatives did! This is a detail of the wood cells in a stem of Sigillaria from the Carboniferous of the USA 🔬🌿⛏️ Happy #FossilFriday!

When you think of fossils you probably think of dinosaur bones, mammoth tusks, or corals and shells. You probably don't think of eyes, guts, and nervous systems, but in some rare cases these soft tissues have been fossilized too!
Check out some examples in this video with Dr. Joe Moysiuk.

It's #MuseumSelfieDay! This year some of our Museum team shared their Museum selfies too. Tell us what your favourite part of your last visit was with a Museum selfie! Tag us on social media @ManitobaMuseum with #MuseumSelfieDay and #MyMBMuseum.
Front cover of Volume 1 of Dr. Diana Bizecki Robson's new publication, "Manitoba Flora: A Guide to the Vascular Plants of Manitoba" with forward written by Shirli Ewanchuk/Black Thunderbird. Book cover is atop a backdrop of an illustrated prairie scene from the Manitoba Museum Prairies Gallery. The Manitoba Museum Shop logo is in the lower left corner.
Plant lovers and outdoor enthusiasts rejoice! Pre-orders for the second run of Dr. Diana Bizecki Robson's new book "Manitoba Flora: A Guide to the Vascular Plants of Manitoba" are open!

Three images of Mosura fentoni. The first two, from left, show the fossil specimen under different lighting conditions. The left photo shows the outline of the specimen with a rounded abdomen and bulby head and tail. The second image, centre, shows the brain and circulatory system of the fossil. On the right is an artist's rendering of Mosura fentoni in life. An underwater creature with two long front limbs covered in spines, three eyes, and a number of fin-like swimming flaps on its sides.
Did you know that in rare circumstances even the soft tissue of organisms can be fossilized?

Welcome back to #TrilobiteTuesday
Here is a pygidium (tail section) from a large Dalmanitid trilobite. This specimen comes from the Lower Devonian Birdsong Shale in eastern Tennessee.
Pleased to share our latest exhibit, featuring some of the most fantastic looking #fossils from the #BurgessShale. Now on display in the @manitobamuseum.bsky.social lobby, so come on by and take a peek!
A view of the headshield of Megalograptus, preserved as reddish-brown cuticle on a pale grey rock. The headshield is generally equilateral in shape, with a rounded front bearing small spiny projections. A pair of round eyes are also located at the front of the head. The surface of the headshield is curved in dense, pustule-like scales.
A fossil of the second appendage of Megalograptus, preserved as dark cuticle on a light grey rock. The appendage is short with robust spines coming off of it.
A view of the body segments of Megalograptus, preserved as dark cuticle on pale grey rock. Four body segments are present, again preserving small, pustule-like scales.
One of the earliest large predatory eurypterids, Megalograptus, for #FossilFriday. Megalograptus is known from abundant - and very unusual - material from the Ordovician of #Ohio, affording an important insight into the morphology of this rather bizarre species. ⚒️🧪
Urgon with some fossils collected on Lake Winnipeg this summer, where further fieldwork will be continued this fall.

An exciting discovery! Urgon found and collected this large specimen while doing fieldwork in southern Alberta this summer.
Manitoba Museum Student Associate and Mitacs Fellow Urgon Snider’s Master’s thesis research is on microfossils. He’ll be working dissolving ancient rocks, extracting tiny fossils, and mounting them for our collections, expanding our understanding of 450-million-year-old ecosystems! #FossilFriday
An all-white frog with dark eyes being held by a brown frog on its back as they mate in shallow water of a pond.
Museum colleagues discovered a completely white wood frog ("Boreorana sylvatica") in a pond just outside of Winnipeg! This is the first record of a white individual of this species anywhere in North America. The white wood frog was likely a female as it was found mating with a normal-coloured male.
