Hello, Could I get an ID on this mazon creek unknown? It has pretty high relief and strong segmentation with makes me think arthropod like a millipede, but I don't see any legs so maybe it's an annelid worm or something.

I'm interested in this Arthropleura fossil and I just want to make sure it's legit. The seller says it's a pleurosegment from the tail of a younger individual. They also point out that there are Mariopteris remains.

Ran across this rock at my neighbor’s property. These are most likely millipede tracks. It’s a big thick rock so getting it home will be a challenge.

I had this Mazon Creek concretion open today. It was collected from the Braidwood biota (freshwater/terrestrial). My best guess is a partial millipede (Amynilyspes?) but I'm not sure and wanted to get other opinions. Thanks for any help. @Nimravis @deutscheben @bigred97 @RCFossils @stats @flipper559 @Mark Kmiecik

A calcite river, that is. Here are two burmite pieces that have a vein of calcite running through the arthropod inclusion. In this millipede sample, the calcite seems to have run along part of the dorsal edge of the animal, displacing it downwards. It is best seen in the images from within the millipede exoskeleton. The calcite flow was influenced by the tissue of the previously deposited inclusion. I thought it interesting that the process of cracking and calcite infiltration and solidification does minimal damage to the older tissue.

Nightmare on Lepidodendron Street. Call the exterminator; there is an 8.6 foot long, 110 pound millipede in my house crawling on the baby. Largest fossil invertebrate fossil ever found, found in England. Carboniferous of course. My note: extant giant squid are larger; I guess that there are no large fossils.

I am somewhat hopeful that this is an example of Amynilyspes (a pill millipede), but would like to get another opinion. It was found open and is a bit worn. @Nimravis @bigred97 @flipper559 A close up of the "tergites"

I found this in the South Yorkshire coalfield (UK) recently (upper Carboniferous). I'm 99% sure its a millipede section but would like some second opinions. I suspect this can't be identified to a genus level but if anyone can narrow down the possibilities that would be great, if it is indeed a millipede. Sorry for the lack of a scale, the camera wouldn't focus on the fossil when there was a ruler. It measures 1cm wide. Thanks, Daniel

Mazon Creek Best of the Best Pleurojulus cf. biornatus
RCFossils posted a topic in Member Collections
The Mazon Creek deposit records one of the best representations of Pennsylvanian aged millipedes. A variety of different types have been found representing several different orders. This is one of the rarer and lesser known types belonging to a relatively new order named Pleurojulida. Pleurojulus lacks spines and has body segments that consist of an upper and lower plate. It is one of the smallest millipedes that can be found in the Mazon Creek deposit. -
Mazon Creek Best Of The Best Arthropleura Cristata Richardson, 1959
RCFossils posted a topic in Member Collections
Arthropleura is one of the most impressive animals that lived in the Pennsylvanian coal swamps. It is also the largest terrestrial animal known from the Mazon Creek deposit and largest terrestrial arthropod of all time. This giant millipede reach an enormous size estimated to be approximately 2 meters! Unfortunately we do not find complete body fossils. Tergites, limbs and an unusual joint structure that connected the leg to the body (rosette organ) have been found. Any Arthropleura material from Mazon is extremely rare. I would estimate there are only a few dozen specimens known to exist. The earliest reported find of Arthropleura in the Mazon Creek Came from George Langford and Eugene Richardson in 1952. They recovered 2 rosette organs. A few years later a complete leg was found. At first these finds were thought to be unusual shrimp. Richardson was the first to realize that they were indeed Arthropleura. This was the first reported find of Arthropleura in North America. Over the next 2 years a few other specimens were recovered. All were found in the same small area at Pit 1. Richardson formally described Arthropleura cristata in 1959. At the time there was some debate as to if Arthropleura lived its life in water or on land. Many trackways have been found at different sites proving that Arthropleura was terrestrial. Gut contents are known from more complete Arthropleura found at other sites showing that it fed on lycopsid spores. Lycopod cones have a similar appearance to a modern day pine cone. There are a few large coprolites that have been collected from the Mazon Creek deposit that consist of these cone bracts. These coprolites have been attributed to Arthropleura. I am very fortunate in having been able to accumulate several fantastic examples of the different body structures of this amazing animal. All specimens were collected from the actual Mazon Creek site. The leg shown is also pictured in The Mazon Creek Fossil Fauna book by Jack Wittry. This first specimen is tergite which would have been positioned on the outside edge of one of the body segments. Most specimens show preserve a bumpy texture. As you can see this one is smooth and might be showing the underside of this plate.- 13 replies

I found this in a coal mining tip in South Yorkshire (UK). It is upper Carboniferous aged. Can anyone identify it please? The only possibility I can think of is millipede. It measures around 1 inch. Thanks, Daniel

Can anyone tell me whether this seller has these IDs right? I figured the first one looks like an Achistrum (sea cucumber) to me. The seller has others that I have questions about too but won't post them all. @RCFossils ?

This fossil is likely a whole new species of ancient millipede. PHOTOGRAPH COURTESY ANDREW MACRAE By Brian Clark Howard PUBLISHED SEPTEMBER 28, 2016 Visitors to a world-famous fossil bed in Canada have discovered a handful of strange specimens that may likely turn out to be up to three new species of large ancient millipedes. The find was made by chance last year in the Joggins Fossil Cliffs, which stretch several miles along the Bay of Fundy. The fossils are being analyzed now in labs in the United States and Canada. Giant ancient millipedes are nothing new for the Joggins cliffs, which are listed as a UNESCO World Heritage site. Since the 1800s, the cliffs have yielded numerous finds, including tracks and segments of millipedes that may have been seven feet long. The new fossil millipedes weren't quite as large: They were likely about a foot long (still relatively big), says Joe Hannibal, a paleontologist with the Cleveland Museum of Natural History, who is studying the new fossils, along with Canadian paleontologist Melissa Grey. The many-legged creatures were likely vegetarians, as most millipedes are, says Hannibal. The leggy animals crawled through ancient forests, which are also partially preserved in the fossil beds in the form of tree trunks. (Watch a video of glowing millipedes.) The new fossils are likely about 300 million years old, says Hannibal, who just returned to Ohio after a trip in the field to Joggins. The fossils are therefore from the Upper Carboniferous or Pennsylvanian period, which is often called the “Coal Age,” since much of the world’s coal originates from deposits of organic material laid down during that time. In fact, Joggins was once mined for its rich coal beds. Fossils were unearthed by miners blasting through its layers of sandstone and shale. The specimens included other millipedes, but no one had seen anything quite like the handful of fossils that were found there last year by guests to the cliffs. The fossils are likely one to three different species, says Hannibal, who is helping with the analysis. They will likely fit into the group known as the archipolypods, which means ancient many feet. Members of this group have been found in Illinois, the Czech Republic, Great Britain, and beyond. Although many of the legs of the animals are quite well preserved, their tops are not in good shape. (See how a millipede toddler learned to walk.) “So we don’t know what their tops were like,” says Hannibal. “They might have had spines, like some of their relatives, which look like big bottle brushes. Or they might have had no spines. So far we don’t have any evidence.” The next question will also be exactly how the new fossils may be related to other millipedes, says Hannibal. (Learn about the world's leggiest animal.) The fossils are an exciting find, says Alton C. Dooley, Jr., a National Geographic explorer who has studied ancient life and is the executive director of the Western Science Center in California. The specimens prove that there are still plenty of relatively large animals awaiting discovery. "By the Carboniferous, life had become so well established on land that there were thriving biomes all over the world," says Dooley. "But the flora and fauna was in many ways so different from what we have today that it’s almost like an alien landscape, and we’re still a long way from fully understanding how all the parts interacted, or even what all the parts were." http://news.nationalgeographic.com/2016/09/fossil-millipedes-discovered-bay-of-fundy-joggins-cliff/?utm_source=Facebook&utm_medium=Social&utm_content=link_fb20160926news-millipedes&utm_campaign=Content&sf37237741=1

I would like to know whether this specimen in a Mazon Creek nodule is the polychaete worm Esconites zelus (incomplete, distal part of the body - as suggested by the "tail-like" structure at one end) or a millipede (or something else)? (I also considered Acanthotelson, but there are too many segments in my specimen). The legs are comparatively long, but badly preserved (and only on one side of the specimen). I know this specimen is no beauty. The total length of the fossil is 20 mm, the width (without legs) about 2,5 mm. Picture 4 shows the counterpart (without legs). Thanks, araucaria1959

Hi All, Well you freeze and thaw, and freeze and thaw, and you think you're never going to find anything really neat and then one day this pops open . I think it is a Euphoberia sp. but I'll wait for others to let me know about that. This image was taken tonight with and an iphone, I'll post better images tomorrow with proper scales but for reference the beasty is just under three inches from snout to tail. Its all there, even the head and legs, and all preserved as a 3D cast. I'll post close up images of the different structures tomorrow as well.
