L.S., Thought it would be fun to share this "chance encounter" I had at a mineral show. The photograph below shows a slab of petrified wood from the Triassic of the Isalo II Fm. of Madagascar. When material from this locality is offered for sale (which happens often and in large quantities), it is usually labelled as "Araucarioxylon" or simply as "petrified wood" (where the latter may actually be better). While most of the wood indeed has an "Araucaria-like" anatomy (see Rössler et al. 2014 for a recent discussion on the nomenclature), I recently was lucky enough to "find" something else. While the left-most photograph may not directly show it, the anatomy of this particular slab is quite different from the common Araucaria-like specimens. I tried to clarify the anatomy by contouring the main structures seen, which hopefully makes visible how this wood consists of multiple rings of perimedular bundles and wedge-shaped structures, showing both centripetal and centrifugal xylem (inward and outward growing regions, per as provisionally indicated by the blue and red arrows). This curious growth form (by modern wood standards, at least) is characteristic for the stems of some groups of Mesozoic seed ferns, such as those from the Umkomasiales order. The best-known genus with this type of anatomy is probably Rhexoxylon (see Archangelsky and Brett 1961), but there are more similar genera, making it difficult to arrive at a more specific identification.

This is said to be a Triassic fossil coral from Guizhou, China. Any idea if it is a fossil coral and what species it probably is? Thanks.

The dinosaur graveyards of the Eastern Cape Province. Karoo Supergroup, South Africa
Oxytropidoceras posted a topic in Fossil News
Exploring the dinosaur graveyards of the Eastern Cape A chance discovery by a local shepherd has lead to a major scientific research program involving palaeontologists from South Africa, the UK and the US in the Karoo Basin. The area is proving to be one of the richest localities for vertebrate fossils in South Africa. by David Paul Ford, Oct 03, 2019 https://natureecoevocommunity.nature.com/users/317374-david-paul-ford/posts/54340-exploring-the-dinosaur-graveyards-of-the-eastern-cape Yours, Paul H.-

Found more tracks! Been digging out and flipping these big chunks of rock since all the tracks are on the underside. I stand corrected on my loose amateur term dinosaurs - archosaurs is the correct term.

Just a question regarding the resin transfer method. I’m looking at a Keichousaurus fossil that I am considering purchasing. While the fossil looks good the seller has stated that the matrix was very unstable and he utilized the resin transfer method to stabilize the matrix. How effective is this method? The matrix looks very thin to me and any inquiries have gone unanswered. I do not have any photos of this specimen but I can direct anyone interested via pm to the very popular site the specimen is selling on. If that’s not a violation of forum rules. Thanks.

Mercer County, New Jersey, USA. Hello, I recently found these two specimens and was wondering if they look good for Triassic tracks. If so, I heard they are very difficult to attribute to a certain species but any information or leads on that would be greatly appreciated (or should I just stick to the Cretaceous streams ). Note - these are NOT from the spot I found my last trackway (#5 on link below), I've just been obsessed lately with finding similar spots close to home. As always, all help is greatly appreciated! -Frank

Found these in East Central Arizona. A deep wash has cut through a rock ledge containing lots of the footprints. Still working on trying to get some of the bigger rock slabs hauled out.

I recently visited Aust Cliffs by the River Severn in Bristol, UK. I believe the fossils are almost entirely Triassic, as the other layers aren't fossiliferous. These were found in broken blocks on the foreshore but most likely originated at the Rhaetian Penarth series at the top of the cliff, as this is where the bone beds are found. I can post more photos if needed, however these are the best I could get at the time on my phone. Any help would be appreciated #1 #2 #3 The black piece is hard and shiny if that helps #4 The shiny part is just over 5mm long. It looks like scales on a fish? Due to the size this is the most I could zoom in while keeping it in focus. #5 This is in a much larger block but the fossil is about 15mm long. Is it bone?

Best Places to Find Fossils on West Coast of England/Wales
its.just.alec posted a topic in Questions & Answers
I am leaving shortly to spend just over a week in England, more specifically in the Liverpool area, and will be taking a day trip along the coast of Wales to Rhyl as well. I've done some basic research and found that Liverpool sits right on top of Triassic bedrock, and Rhyl on top of Permian bedrock. Are there any sites that would be within my realm to visit and collect at? If so, are there any rules and regulations that I, an amateur from outside the country, need to know about before I go? If there are none, are there any noteworthy shops that I may be able to visit where I can buy some local specimens? I enjoy bringing home a fossil from my trips each time I travel somewhere, the more local the better. Thanks in advance! -

Picture Heavy! On my first day in Millard County, I started out at the U-DIG quarry. I got lots of trilobites, but nothing too spectacular. (I'll share them in a separate post as there is quite a bit of prep work to do!) Honestly, I got a bit bored at the quarry. Sure, I enjoy digging fossils, but the challenge just isn't there. So after four hours, I decided to drive through Marjum Pass to Cowboy Pass. This is the view exiting Marjum Pass. (That is a truly epic drive on its own, but I didn't stop at any of the fossil sites in there!) Almost there! For those that don't know, distance and time behaves a bit strangely when solo in the desert. Finding road signs is even stranger. If you do decide to do a Millard County run, you'd better be able to use a topo map and a compass because you cant trust GPS maps and mobile phones have no service out here. I found that even the road atlas was untrustworthy. It took me three months of research to pinpoint the exact locations of the exposed Thaynes Formation areas of the Pass. Doing the homework paid off as I was able to find the "easy" site almost immediately. I'm not really into giving out exact locations, but I will say "The Book" is correct and accurate and that this photo shows the landmark referred to in an old Millard County rockhound guide. I know I could have just asked folks where they were, but a big part of this hobby for me is the satisfaction of confirming my research skills. One can easily drive to the "easy" site, but the other two (actually three...) require a pretty rugged hike. However, as you are about to see, it is well worth it. I found my first in the overburden some hack left behind. In fact, at the easy site I didn't even need to use any tools as whoever was there last ignored dozens of nice specimens! I will also add, I hope it wasn't someone from here...as I cleaned up all your %#!$%^&* trash for you. Three full bags of garbage and you left a virtually brand new gad pry under the pile of beer cans. Thanks. I needed a gad pry later! Anyway, Here are some of the specimens I collected from the various sites. Most of them need lots of prep work. Here's a few as they were found: I'll post more pictures at a later date as there is a lot of prep work to do on many of the specimens! So, in short, Cowboy Pass is well worth the excursion. Be prepared to do some real work, and study up on the site before you go. Also, don't be a jerk and leave a mess like the one I found...that is how public lands get closed to the public.

Hi all! I'm Tiffany and I'm in Cape Town, South Africa. I have an Honours degree in Archaeology, but I have been working as a fossil preparator for nearly 4 years. I used to work at our Natural History museum but I have very recently taken my preparation skills private. I primarily work on therapsid fossils from the mid to late Permian (sometimes spilling into the Triassic) that occur here in South Africa. There is an area called the Karoo which fortunately is very rich in beautiful fossils! When I started working on fossils I didn't know much about them, but over the last few years I have learnt so much! It has taken time and dedication to get to the level of preparation that I am at, with many hours of sitting dead still. I work on microvertebrate fossils and I love working on teeth especially! I've attached a picture of a juvenile youngina (same as profile picture just better quality) that I worked on last year, and the scale bar you can see is 1mm gaps (sorry - we're all metric here!) so you can see the scale of things I work on. I'd like to learn more about what equipment people around the world use for different specimens, as I am in the market to buy my own equipment. I also hope to contribute about fossil preparation and what I have learnt myself! There is still so much out there!!
