Day Two ; Locality Two (or Seven if you include Day One) Prepping and Retail, Erfoud, Morocco. 20th February 2019 Erfoud town itself is famous for its beautiful fossils, its skilled fossil preppers and also for its wide variety of fakes, composites, good and bad repair jobs and utter frankenfossils. A large percentage of fossils from Morocco that are available in shops and on the internet the world over originate from here or pass through the place. Fossils are sent here for prepping from all over the south and then sent from here everywhere in the country and abroad. There are many little shops, prepping centres with huge attached shops and 'museums which are really pretty much just shops as well. Top Tip :The prices here are about ten times the price of the prices in the little shacks on the edge of town or elsewhere in Morocco, but haggling can reduce the cost significantly. Many places have 'fixed' prices, but they're actually always negotiable. This time, we went to the one my friend Anouar, who is a tour guide, takes his tourists and I was asked politely not to accuse the owners and chap who'd show us around and do the chat, of having fakes or wrong info, so i had to bite my lip. We asked if it was okay to take photos and they said yes, which I was surprised about, but I guess it was because Anouar was going to use photos for his own purposes and this would involve advertising the shop. Top Tip : You will see a lot of fixed prices in Moroccan Dirham in the pieces and shelves. Divide by ten to have a price in US dollars. Because we were with Anouar, we were told everything is 50% of the marked price, but I suspect they often do this anyway, "Special Berber prices, today only". I've heard that before. And you can still haggle to get something way under that 50% and you just know they'll still be making a good profit. I didn't buy anything. Little local stores are more my line anyway - I rarely shop in supermarkets. Here is the entrance where you can see huge plates ready for prepping and polishing, some have been cut into pieces and they glued back together it seems to me, I know this happens with the crinoid beds, so i guess it's true of the orthocerid and goniatite stuff too. Some just look cobbled together because of the circular saw marks when cutting out upper layers.With these, polishing will remove the grid lines. These sheets are from the local area and contain the goniatites and orthoconic nautiloids we were walking on earlier, but from a better quality, less eroded and distorted source. Famennian, Upper Devonian, I think. This photo shows one of the trenches they dig to reach the best quality material, similar to the ones i was walking along earlier this day : Below, somebody walking on the slabs and some maps of the the world at different times in it's past, showing continental drift. : Notice these are not the famous black orthocerid marbles that come from elsewhere. The picture of Spinosaurus is a bit misleading, as you all know, it's not found in these marbles or in the Erfoud area. In fact there is very little Kem Kem material available here these days, though there was in the past. I suspect the Kem Kem area probably has it's own facillities nowadays.
Taken from my blog post: http://redleafz.blogspot.ca/2013/06/cheverie-hantsport-nova-scotia.html I had planned to go back to Blue Beach in the Avonpart area for a while now. The site and other neighboring lcoations have always yielded wonderful specimens and I was itching to get back on the beaches and under the warm Nova Scotia Sun. I hadn't had the chance to hit the road for weeks due to some illness, but seeing the opportunity to go on a day trip, I took it. 1st stop Cheverie (red), 2nd stop Hantsport (red) 3rd and final stop Parrsboro (blue) (red path - from Moncton to stop #2 in Nova Scotia ) (blue path - from stop #2 to #3 in Parrsboro, then back to New Brunswick) I had planned to make a few stops in the Windsor area along the coast. I'd decided to check the white beaches of Cheverie and its gypsum cliffs. These evaporites were left from an ancient body of water, the Windor Sea. Gypsum makes up big sections the area, and is intermixed with very fossiliferous limestones and shales, from Cheverie to across the bay at Blue Beach, which would be my second stop. Stop #1 Cheverie is a few hours from Moncton, about 3 hours drive one way. I took the scenic route via Walton to drive along the coast. The drive itself was excellent as the weather couldn't have been better. Sunny with +30 degrees Celcius along the coast, what more can one ask? I left Moncton at around 7:30am and arrived at my first destination at about 11am. There was some road construction so that added a few more minutes to the trip. Parking on the side of the road, I grabbed my camera and proceeded down the beach. These cliffs are mostly composed of gypsum, with some limestone outcrops jutting out from time to time in some areas. Gypsum outcrop Horsetail White beaches of Cheverie After a short walk on the beach, I packed my gear and headed on the other side of Avon River, to Hantsport. My second stop that afternoon was Blue Beach down Bluff Road. I've been here a few times before and there is so much to see. The outcrops at Blue Beach are abundant with fossils from the Carboniferous Period, with layers transitioning between land- and water-type paleoenvironments. Stop #2 The shale and mudstone are rich in fossils, with numerous brachiopods and bivalves, fish scales, bones, and arthropod trackways. Some of the other sediment type such as some of the sandstones contain various well preserved plants and tetrapod tracks. Scales Shells Bone Arthropod and worm feeding and resting traces Outcrop where loose material contained many fossils Molluscs in groups Bones Possible trackways? Tree segment with bark impression Diplichnites (arthropod tracks) Trackways (?) - fossil plant part of the sandstone block I spent a couple of hours on the beach and kept coming up on a lot of material to look at. When it was time for me to leave, I noticed that I had only walk a tiny fraction of the beach that I had initially intended to. This site deserves another visit really soon from yours truly to check the rest of the beach. Having spent most of the day on the other side of Cumberland, I thought that it would be nice to have a bite in Parrsboro, across the Minas Basin. It was 4pm and I realized that it would be a 2 hour drive, or detour, but the Sun was out in full and the drive would be nice, especially driving along the coast. I packed up my stuff, and made my way towards Parrsboro, which would end up being stop #3. I drove into town and went down Two Island road to finally end up at the Harborview Restaurant, which had opened a few weeks earlier for the season. The food's great and you just can't beat the view. View from outside the restaurant Even though I wasn't able to hit all the spots I wanted, it was a very nice and productive day. Being cooped up in the house with the flu for two weeks, it was nice to catch some vitamin D from the good fiery globe in the sky. I arrived back in Moncton at about 8:30pm, but I could have kept on going. I will definitely have to swing back by that area very soon. Till then, cheers! - Keenan
