Today is World Maritime Day. With over 13,000 kilometers of coastline, Nova Scotia is shaped by the sea. Take time to explore the stories of our seafaring past, present, and future. #NovaScotia

Found this 80,000 year old seed in #MastodonMud at the museum today. Will it sprout? @novascotiamuseum.bsky.social

For #FossilFriday - ancient DNA shows the #NovaScotia mastodons are older than thought, and have migrated into the Atlantic region multiple times over the past 500,000 years. In Science Advances www.science.org/doi/10.1126/... ⚒️

On my desk for #FossilFriday - these small bones (Northern Leopard Frog) and the spruce cone being removed from a small block of 80,000 year old mud collected during the 1991 Mastodon dig. These have been in a freezer for over 30 years! Will the 80,000 year old spruce cone have viable seeds?

Please come and visit us again. I would be so pleased to show you all the sites, modern and fossil.

In Travels to North America and Nova Scotia (1845) Lyell published this lithograph of bird tracks in mud that he collected in 1842. Today, as I sit on this same shore, I can appreciate Lyell watching these delicate birds and thinking about deep time. #geoheritage

Last bit should say “Cracks seem unrelated to tracks here.”

Tim Fedak PhD @timfedak.bsky.social · Aug 6

The mudcracks seem to be based on the mass and orientation of mud, flatter regions have larger “tiles”, wider spacing of cracks and more vertical areas have more tightly spaced cracks, smaller tiles. Tracks seem more related to spacing here.

The delicate bird tracks are from the small Semipalmated Sandpipers. While doing a drawing study, the birds ignore you and go about their business.

Today - I'm taking a road trip to #Kentville #NovaScotia to search for tracks preserved in Bay of Fundy mud. In 1842, Dr. Webster sent samples of rain prints collected from the muddy banks of the Cornwallis River to Charles Lyell. The rest, is geological history! ⚒️ archive.org/details/quar...

The first of its kind in the limestone unit.

Tim Fedak PhD @timfedak.bsky.social · Jul 18

It's a new specimen and from the Windsor Group, so yes, it is younger.

Kissing fish! For #FossilFriday - the latest view of the Platysomid fish from the Early Carboniferous of #NovaScotia found by Dr Mo Snyder and Jesse Demaires-Smith from Acadia University is 2023. ⚒️ Fossil and counterpart - look like two fish kissing.

This area has been previously mapped as Pembroke Formation, near base of Windsor Group. Early Carboniferous.

Tim Fedak PhD @timfedak.bsky.social · Jun 22

This is a Carboniferous. A small fault bound outlier surrounded by Wolfville Formation.

In August of 1842, Charles Lyell visit a fossiliferous limestone on the shore of the Debert River, #NovaScotia. Today, I found the fossiliferous limestone, and am impressed with the view that Lyell enjoyed so many years ago. ⚒️
