“There was no land as we know it today as soil and plants…all above the water was just bare granite and volcanic islands…maybe a little bit of algae growing wherethe rock met the seas. Noting else. No trees, no plants, no grass and certainly no flowers. But the seawas full of life. Some places the sea bottoms was carpeted with crinoids.”“How do you know?”“because some of these pieces of shale have crinoid fossils so thick that the shale is hard to find. At somepoint whole populations of crinoids died another bodies settled into the mud only to be changed by chemicalaction over millions of years into he fossils we can find littered here and there on this shingle beach.”“What did they eat?”“Nautiloids were predators. They ate other creatures, especially little trilobites. The inland sea tamed with life.A Nautillus…descendent of the Ordovician nautalloids that lived 450 million years ago“Most nautiloids did not survive the five great extinctions that devastated living things on our planet. Most but not all.One nautallus can still be found in the deep tropical waters of the Asian Pacific Ocean. Not easy to find for it dives intothe dark depths of the ocean in day time and only rises to kill when the moon does. A scary but beautiful creature.”“The creature that seems to have been very common 450 million years ago, Crinoids looked like plants.As a matter of fact some called them ‘sea lilliies’. But they were animals. At the bottom of their long neck (spine if you will),crinoids had root like feet that anchored them to the bottom of the ancient seas. At the top of their long neckswas a bunch of tentacles that waved in the ocean currents grabbing plankton and other bits of edible thingsthat drifted by. The plankton was taken by the tentacle and dropped or placed in the crinoid mouth at the tentacle base.The food was chewed and the good parts were kept. The rejected parts were spit out. A crinoid had a mouth anda rectum in the same place.”“Could they move?”“Yes, slowly the feet moved from stone to stone.”“Were they common?”“Very common…they lived in great clusters wherever plankton moved on ocean subterranean currents.”“And if current changed they walked to a better spot, right? How big were they?”“The fossils I have found that look like crinoids are quite small but I read somewhere that the crinoids couldbe as much as 140 feet long.

EPISODE 802 REFLECTIONS ON FOSSILS ON RATTRAY MARSH SHINGLE BEACH, PART 1
alan skeochMarch 11, 2020“Let’s take a walk, Marjorie,
“Where?”“There is a shingle beach AT the Rattray Marsh…good place to start.
(Note, the Rattray Marsh is one of the wonders of the City of Mississauga, It slumbers behind a rock strewn beach of Lake Ontario. The southwest quadrant ofMississauga…almost approachable….definitely unforgettable.)
“This Shingle Beach is one of the marvels of Mississauga…strewn with small flat slabs of water washed shale.”
“Wouldn’t a sand beach be more charming?”“Not at all…no story obvious in grains of sand….but this shingle beach can be read like a book.”“Easy to trip and fall here.”“Right…if you do trip and fall you will find yourself among interesting company.”“Piles of flat stones.”“Piles of blue shale….”“Do you know how old these pieces of shale are?”“I don’t even know what shale is”
“Shale was once mud…pressed by the weight of untold piles of mud…heavy…so much sothat this ancient mud became sedimentary rock called shale.“Our city, Mississauga, sits on top of a vast expanse of ancient mud…for that matter the ancient mudonce ground and dried became the cement that holds up all the buildings in Mississauga.And for seventy years, 1850 to 1920, slabs of this shale were pried up by crowbars right fromthe shingle beach where we are standing, pried up in great slabs, manhandled onto schooners and sailedto Toronto as the foundations of all the great buildings of the time.”“Do you mean the Stonehookers?”

EPISODE 799 WHAT DOES THIS PILE OF ROCK SAY?alan skeochApril 17, 2023We descended through the Niagara Escarpment to the QEWWHAT DO WE KNOW1) The Niagara Escarpment we know today is the result of geological processes that began more than 450 million years ago when the limestones, dolostones, shales, and sandstones of the Escarpment’s bedrock were formed.2)
1) ONE CANNABIS GROWER SAID TO CTV: says he has another three years on his lease. With a rent of $6,000 per month, he admits that “bankruptcy may be the only way to get out of here.” He spent nearly $300,000 on his retail store, with his family lending him the bulk of the money.
“Licensing cost me $10,000 for this location. Then I had all my renovations, that was about $150,000. Then I had rent and operating costs, that’s $60,000. Then I had an inventory of $50,000. So, we’re already at $280,000, and that’s not including payroll for employees and overhead like that,” Kostanyan told CTV National News.
