Found on an island in the Canadian Arctic. I think it's a Mosasaur tooth, but I'm really a newbie at this. The whole piece is about 3 inches in length. Thanks for any help!

Saskatchewan researchers have reportedly discovered an extensive network of blood vessels preserved in the fossil of a tyrannosaur rib. This discovery, if confirmed, would be the first of its kind.

Hi, I logged in here a while ago and have been checking things out every once in a while, particularly since I'm interested in the Canadian side of things. Now I think it's time to introduce myself. I'm a baby-boomer from the 50's, born in England, grew up in Brampton,Ontario,Canada and have been living in the south of Germany since 1987. I began collecting over here, so I haven't had much firsthand experience in Canada or America; just a bit of digging on a few short trips since I moved here. I began with minerals, but I soon moved on to Fossils, first of all since they're readily available in my part of the world(Swabian Alb-Jurassic Age) I specialize in the Aalenium, particularly the upper part, but I'm interested in practically everything, since the themes of the development of life on earth and our planetary metamorphosis are extremely fascinating for me. My collection fills 5 showcases and a number of shelves and spreads on into my preparation room in the basement. It's made up practically only of my own finds over the years. I'll attach a few photos to give you an impression.(If I understand correctly, each Photo can be up to 2 MB. Let's see what happens.) I joined the German fossil Forum "Steinkern.de" in 2008 and am active there writing articles and working as an editor. I've also recently begun contributing to hobby magazines and maintain contacts to professionals in the field. I'll take another look through the forum now to see where I might be able to contribute something. I'm looking forward to hearing something from you; particularly you Canadians. (Don't let that put you Americans off though I lived in Pennsylvania for 3 years) Best wishes, Roger

Canadian Amber (Allenby Fm., 52.5-48 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
3.0g of amber, from the same lot in the two associated entries. This mid to late-Ypresian material comes from an old site near the abandoned mining town of Blakeburn, which site and its gangue piles are now technically owned by a coal mining company (although the existing legal claim of the individual who collected this amber is being overruled by the company). The amber is found primarily in association with Metasequoia sp. remains/imprints, however Pinus and Pseudolarix (among others) remains are also found in a lesser quantity at the site.© Kaegen Lau

Just a note that James Cullison's 1944 monograph on the rocks and fauna of the upper Lower Ordovician of Missouri and Arkansas is now freely available for download or perusal at https://archive.org/details/paper-cullison-1944-the-stratigraphy-of-some-lower-ordovician-formations-of-the This publication has always been devilishly tough to get a hold of. A nice systematic paleontology section deals with the many gastropods and other mollusks as well as the less diverse brachiopods, trilobites, and sponges. The monograph covers the following formations as currently accepted in Missouri: • Smithville Formation • Powell Formation • Cotter Formation • Jefferson City Formation Enjoy and share as you like. Full citation: J. S. Cullison, 1944: "The Stratigraphy Of Some Lower Ordovician Formations Of The Ozark Uplift." The University of Missouri School of Mines and Metallurgy Bulletin Technical Series, Vol. 15, No. 2, 112 pp + 35 pl.

Canadian Amber (Allenby Fm., 52.5-48 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Rough amber from an old site near Coalmont, British Columbia. The original site is now closed to collecting, since a mining company somehow got a court injunction and has "jumped" the owner's legal, active long-standing claim. The claim owner has informed me that he is not able to collect larger specimens (>3g fraction), as he had been able to in the past.© Kaegen Lau

Looking for help with this Early Ordovician (Floian) trilobite from the Powell Dolostone of Arkansas, USA. The specimens (GRAY FIGURE below) were identified by Taylor (1968) as cf. Lannacus nericiensis Wiman, but that species (now a species of Megalaspides) doesn't seem like a great match, as the author notes in the paper. In fact, I'm not sure that proper Megalaspides even lived in North America. Last week, an Arkansan found another asaphide specimen (MAIZE AND BLUE FIGURE below) in these same rocks, which may or may not be the same species as the specimens described by Taylor. My question: Could these all be specimens of Isoteloides canalis? That species is already known from the Powell Dolostone in Missouri per Weller & St. Clair (1928) (as Isoteloides whitfieldi, now a subjective synonym of Isoteloides canalis). Or are these instead specimens of a distinct Powell asaphide, and if so, what genus & species? Thanks in advance. 1959 Treatise blurbs for Isoteloides and Megalaspides are in the BLACK AND WHITE FIGURE below. Here's Taylor (1968): https://scholarworks.uark.edu/cgi/viewcontent.cgi?article=3056&context=jaas Here's Weller & St. Clair (1928): https://share.mo.gov/nr/mgs/MGSData/Books/Volumes/Geology of Ste.
