This important new paper from Allart Van Viersen and Gerry Kloc @GerryK should cause an indeterminable number of revised labels around the globe! Hollardops mesocristatus (Le Maître, 1952) has been restricted to the holotype from the Chefar el Ahmar Formation, Algeria. "The replacement of the unidentifiable name-bearing type of H. mesocristatus with the poorly preserved paratype of evenly imprecise geographic and stratigraphic provenance would be pointless. Therefore, we prefer to restrict H. mesocristatus to the holotype. This is a rigorous measure but one that enables the objective recognition of distinct species, albeit with the knowledge that one of these might potentially belong to H. mesocristatus when future collections at the type locality are conducted. Still, that would require the near-impossible identification of the specific bank that the holotype was extracted from as well as sufficient specimens to span a range of holaspid instars, in order to validate an unambiguous relationship with the type." This is the revised and updated list of the valid species from Morocco: Hollardops aithassainorum – Chatterton, Fortey, Brett, Gibb & McKellar, 2006 (lower Eifelian, Morocco) Hollardops angustifrons – Van Viersen & Kloc, 2022 (upper Emsian, Morocco) Hollardops boudibensis – Morzadec, 1997 (upper Emsian, Morocco) Hollardops burtandmimiae – (Lieberman & Kloc, 1997)(upper Emsian?, Morocco) Hollardops hyfinkeli (Lieberman & Kloc, 1997) (upper Emsian?, Morocco) Hollardops klugi – Van Viersen & Kloc, 2022 (lower Emsian, Morocco) Hollardops kyriarchos – Van Viersen & Kloc, 2022 (upper Emsian, Morocco) Hollardops luscus – Van Viersen & Kloc, 2022 (upper Emsian, Morocco) Hollardops multatuli – Van Viersen & Kloc, 2022 (upper Emsian, Morocco) Van Viersen, A.P., Kloc, G.J., 2022 Functional Morphology, Coaptation and Palaeoecology of Hollardops (Trilobita, Acastidae), With Descriptions of New Species and Two New Genera from the Devonian of Morocco.

This is a beautiful, 4.7cm long specimen of Metacanthina issoumourensis (Morzadec, 2001), a fairly common species from the Devonian of Morocco. It was quarried near Lghaft. There has been light restoration on the glabella, but otherwise the shell is intact.

Hi I have this small bug from Morocco, but i dont know the species. I checked on google, reedops and drotops look close. Thank you for your help

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.

Howdy all. I'm one of those that value correct id's when it comes to fossils, so I thought that I'd post some common misidentifications often seen in anything from gift shops to proffessional collections. If you know any other misidentifications you are welcome to post them here First up are the "Orthoceras" slabs coming out of Morocco (all these misidentifications are of moroccan fossils). Orthoceras currently only contains 1 species, which is only known from my general area (Northern Europe), based on my research, the species originally called "Orthoceras fluminese" is the correct ID for the moroccan orthocones, and this species is today known as "Orthocycloceras fluminese". Second, another paleozoic invertebrate, the Moroccan calymenids are very common and are often labelled as "Calymene" or "Diacalymene", but neither genus exist in Morocco. The correct species for these trilobites is "Flexicalymene ouzregui". Third, we have the Moroccan Globidens teeth, these are often sold as "Globidens aegypticus", a species that according to both Wikipedia and the Paleobiology Database doesn't exist. The name you're looking for is "Globidens phosphaticus". Lastly, we have another mosasaur. "Mosasaurus anceps" or "Prognathodon anceps" teeth are quite common on the market, but they do in fact belong to "Liodon anceps", sometimes teeth labelled as "Prognathodon sp." Will belong to Liodon as well. I hope this helped

Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.

can anyone help me identify this trilobite? it will soon be mine but it was mislabelled as Morocconites malladoides which it’s certainly isn’t. have been told it might be a Reedops cephalotes

Are my fossiles genuine or fake?
buraqing34 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, im new in fossiles collecting, absolute new beginner. I wonder if my fossiles are genuine or fake, i was so proud of my collection but after i learned that there are many fake Moroccan trilobites on sale, i had suspicions. There are some holes in trilobite and some stuff on it, could be glued which is fine because its age matters to me most, it could be glued no problem. I put them under a plastic sheet but if you wish i can take them out to take better pictures.

Hi FF, I recently bought a "raptor tooth" that came from the Kem Kem beds in Morocco. I wanted to make an information card for it in the display (it’s a gift for a young paleontologist), but the description said “These small theropod dinosaurs from the Tegana Formation have yet to be described, primarily due to lack of articulated bone material having been found in the formation." Someone told me that it was most likely from an Abelisaur (rather than a raptor), and recommended that I ask for advice on this site. I'm just trying to find out more about the fossil and the best thing to put on the display card. This is part of the description they gave me: Late Cretaceous (100.5 million years ago - 66 million years ago) Taouz, Kem Kem Basin, Morocco Specimen Size: .73" long or 18.542mm I've attached some pictures of the tooth, and I hope that I followed the post rules correctly. Any advice you have would be appreciated. Thank you! DG

This is a silver pick find that I've had for a while. I'm stuck here in a snowstorm and really need a fossil fix. So I thought I'd give this a try. Could this be a Scyphocrinitid from the Erfound beds ?

we got some time ago some really nice trilobites from fezouata-biota in morocco. I am not very familiar with trilobites and use the famous book from Patrice Lebrun to determinate and got today some new great infos from Scott (Piranha). So, I hope I am right with my name for trilobite nr. 1: Foulonia What do you think? It´s a small one, including spines less than 2 cm

I love to show a really really nice fossil from our collection. Small stone (8 cm long) with two rare Acantharges mbareki from morocco / l´Ougnate, Devonian. Very special is to see both side. One is from the top, the other from the bottom, showing the hypostom (I think its the Hypostom, round but position fits) both are approx. 1.5 cm long enjoy

Hi everybody! This my dinosaur collection. This is my Hell Creek and Judith River shelf. It's a bit empty but I'm working on getting more fossils. I also have a replica Triceratops skull that I had 3-d printed. This is my tyrannosaur tooth fragment from the Hell Creek fm of Harding County SD. I'd gotten a bag of micro-matrix from hell creek and I got some ossified tendon fragments A partial Pachycephalosaurus? caudal vertebra from Harding County SD A jaw fragment from an indeterminate hadrosaur from the Judith River fm of Hill County Montana And an Edmontosaurus spitter tooth from the Lance fm of WY And now onto the Moroccan fossils I have a spinosaur tooth and some mosasaur teeth, the biggest of the mosasaur teeth being 2 inches. A Spinosaur indet. too

Can radioactive fossils damage other specimens?
Maniraptora posted a topic in General Fossil Discussion
I know next to nothing about radioactivity-- enough to know licking fossils is inadvisable, although I'll admit that wasn't terribly disappointing news. What I'm wondering is whether specimens not radioactive enough to endanger a person are capable of damaging other specimens. Is there a need to segregate displays here, or am I just confused about the mechanics of this? My specific reason for asking is that at the moment I'm planning for my current favorite mineral specimen (which I am babying forever), an almandine garnet from Broken Hill, New South Wales, Australia, to share a small shelf area with a tooth from the phosphate deposits in Oulad Abdoun Basin, Morocco and a few dinosaur bone pieces from the Hell Creek Formation of Montana (one from Dawson County) and Lance Creek Formation of Niobrara County, Wyoming. The shelf is not enclosed, by the way. Thanks for your help! -
This is the last batch of some unidentified fossils that I picked up in an auction - they accompanied a massive whale vertebrae which was the main lot. The other items were teeth (likely Moroccan Cretaceous) and two claws that turned out to be casts. 1 & 2 - two socket bones that I don’t know the physiology of, the larger is about 4” long and 770g 3 - a vertebrae, 750g 4 - a horn-like piece that may or may not be a fossil, the material is such that I can’t see bone or keratin structure 5 - an small, odd-shaped bone fossil 6 - a long vertebrae, very ferrous (3” but 700g), some carbonised material on the outside 7 - a piece of bone, lovely structure 8 - a tail (?) vertebrae, some damage 9 - a light and heavily repaired oddity Looking forward to hearing your thoughts / insights.
