A beautifully fossilised sea scorpion for this #FossilFriday! Eurypterus remipes was a species of eurypterid that lived 421 million years ago during the Silurian Period. This example was found in Ontario, Canada!🇨🇦
A one-tusked mastodon for this #FossilFriday! Mammut americanum roamed North America 12,000 years ago. This example was found in Ontario, Canada. Its skull shows evidence that this one lived much of its life with just one tusk, rather than losing it after death.
I'm kicking off 2025 and my third year of posting #FossilFriday with an arthropod from one of my favourite periods to study! Yawunik kootenayi was a species of megacheira that lived 506 million years ago during the Cambrian. It was found in Kootenay National Park, BC, Canada!🇨🇦
Thank you! The ROM is a great place and the Trilobite wall is a real highlight. I found out last year that they are all the actual fossil with only one cast in the cabinet (I thought that was a cool detail)!
For the last #FossilFriday of 2024, I have Kolihapeltis chlupaci! This trilobite was found in Morocco and dates back 389 million years to the Devonian Period.
Wishing everyone a happy Christmas! I can't think of a better way to round out the Fossil Advent Calendar than to reveal Mammut americanum behind our final door! This mastodon lived 12,000 years ago. Notice that this specimen is missing a tusk! #AdventCalendar
Like all good advent calendars, Day 24 is our penultimate (and not last) door on the Fossil Advent Calendar, and it’s also #TrilobiteTuesday! Boedaspis ensifer lived 464 million years ago during the Ordovician Period. This spiny trilobite was found in Russia! #AdventCalendar
Day 23 of the Fossil Advent Calendar reveals a species found only in Texas! Seymouria baylorensis lived 275 million years ago during the Permian Period. Its taxonomic status between amphibian and reptile (or somewhere in between) has been debated! #AdventCalendar
A nearly 3-metre-long fish behind Door #22 of the Fossil Advent Calendar? That’s exactly what we have! Lebachacanthus senckenbergianus was a freshwater shark that lived 295 million years ago during the Permian Period. It was found in Germany! #AdventCalendar
Day 21 of the Fossil Advent Calendar gives us Dendrerpeton acadianum! This amphibian lived 316 million years ago during the Carboniferous Period. This fossil was found in Nova Scotia, which was near the equator during that time. #AdventCalendar
Described in 2010, I have Herpetogaster collinsi for this #FossilFriday, complete with an amazing model to accompany it! This invertebrate lived 506 million years ago during the Cambrian Period and was found in the Burgess Shale, British Columbia, Canada!
Not only is it #FossilFriday, it’s also Day 20 of the Fossil Advent Calendar! Behind Door #20 we have Eramoscorpius brucensis, an aquatic scorpion that lived 432 million years ago. It may have used its leg structure to venture briefly onto land! #AdventCalendar
Door #19 of the Fossil Advent Calendar gives us another dinosaur! Protoceratops andrewsi was a ceratopsian that lived in Asia 80 million years ago during the Cretaceous Period. #AdventCalendar
Behind Door #18 of the Fossil Advent Calendar we have Platecarpus coryphaeus! This marine reptile, a mosasaur, lived around 83 million years ago during the Cretaceous Period. This specimen was found in Kansas, USA! #AdventCalendar
Another #TrilobiteTuesday, another trilobite in the Fossil Advent Calendar! Door #17 gives us Metopolichas platyrhinus, which lived 464 million years ago during the Ordovician Period. This specimen was found in Russia. #AdventCalendar
