Just sharing some Fossil Brittle Stars from the Eocene era. Found in remote area of Upper Sespe Creek drainage of the Los Padres Mountains in Southern California. Fossil site location help credit to R. L. Squires 1994 paper on Macropaleontology of Eocene marine rocks, upper Sespe Creek area, Ventura County, southern California.

Curious to know how fake this piece is. Color enhanced feels like a given, but is any part of it real? Thank you in advance.

Hi everyone! I recently acquired these two at a fossil show at a pretty good price. Thing is, I'm not super familiar with starfish and brittle stars. They're Moroccan so I figured there might be some funny business because, Morocco. I suspect three of the arm ends (in the upper left pic they are the upper right and left and lower right arms) on the starfish and the very tips of the brittle star arms, but if anyone sees anywhere else that might be fake or restored or if those areas look okay it be great if they can point it out. Any insight is appreciated as always!

Hello everyone, and I hope you've had a good weekend. I have purchased this brittle star found in the Solnhofen Limestone. Here are the two images they have provided - in any case, they're probably higher quality than my phone would be able to take. They have labelled it as an unidentified species, and that it is known to have grown to a maximum of 3 centimeters across. The slab my specimen is on is 3 cm itself. What should I label it as in my display cabinet? Thanks for the help, it has been much appreciated over the last few weeks.

Today I went to visit a friend of mine who purchased a flat of swatara gap material recently from an old collection. After hanging out and chatting for a bit he mentioned he had something to show me. He revealed a flat of incredible material to say the least, Two Acidaspis, a nearly perfect 3 inch Isotelus, and a massive Taeniaster flanked by two carpoids. The other specimens in the box were more common but impressively complete. I made an offer on the spot, after negotiating for a little we made a deal and I went home with the collection I knew most of the specimens had been collected by my good friend Kerry Matt as he had mentioned the specimens to me while collecting before. After talking to Kerry we agreed I’d return a few of the specimens to his collection in a trade. While I have all the specimens I thought I’d share them as they the species are often never seen from Swatara. See attached images of the specimens for the details. For context about Swatara Gap read: R.I.P Swatara Gap Top to bottom: Isotelus gigas: collected by Kerry Matt in 1984. Acidaspis cincinnatienis Acidaspis cincinnatienis Taeniaster spinosus with 2 carpoids belonging to the genus Ateleocystites. Ateleocystites Ateleocystites note the intact tube feet on the brittle star arm next to it.

I am struggling to find proper information on how to identify different brittlestar genuses, so if anyone has a good resource for that, that would be great as well! Found at place de la Crevasse near Equihen, when splitting open a fallen block of layered, clayey shale. Scale is in cm.

Here are some of my finds from spending a few hours on Wednesday, October 26th, in the Graysonites wacoense Zone of the Grayson Formation, Washita Group of north Texas (Early Cenomanian, ~97mya). This particular site exposes a micromorph layer full of thousands of tiny dwarfed Mariella bosquensis and M. rhacioformis ammonites plus a wealth of other taxa like various urchins, brittlestar fragments, shark teeth, many gastropods & pelecypods, etc. Those familiar with the Del Rio exposures of further south in central Texas (particularly the now closed-to-public Waco Pit in McLennan County), should recognize much of the fauna to be found at this site as it is laterally equivalent to those and faunally nearly identical, differing only slightly in the rarity of homomorph ammonites at this site vs further south, as well as slight differences in preservation/lithology. The following is just a fraction of what I found: One of thousands of dwarfed Mariella bosquensis (Turrilitidae) ammonites: Cretalamna cf. catoxodon (Otodontidae) shark tooth, this species was first described from the Cenomanian of Western Australia by Siversson et al., 2015 where many species were split out of the broad C. appendiculata: Goniophorus scotti (Saleniidae) sea urchin fragment: A tiny Stoliczkaia texana (Lyelliceratidae) ammonite: Arm fragments of Ophiura graysonensis (Ophiuridae), a brittlestar. I hope to find a complete specimen or at least a central disk at this site soon: Another Goniophorus scotti (Saleniidae): Some more dwarf Mariella bosquensis (Turrilitidae) ammonites: Found in just a few seconds of searching in one spot: Neithea texana (Neitheidae) scallop: Praescabrotrigonia emoryi (Pterotrigoniidae) clam: cf. Margarites (Margaritidae) gastropod: A very small Cymatoceras hilli (Cymatoceratidae) nautiloid: Imprints of the pellet-lined burrows of mud shrimp (the ichnogenus being Ophiomorpha). These almost certainly belong to Meticonaxius rhacheochir (Micheleidae) which is known from both the older Pawpaw Formation and the younger Britton Formation, the latter of which contains abundant identical Ophiomorpha which have been found with the bodies of M. rhacheochir preserved inside: Chondrites trace fossils: Bivalve shell fragment conglomerate slabs consisting mainly of Texigryphaea roemeri oyster and Neithea texana scallop fragments: A mass of white nodules which I presume are likely fossilized rhodoliths, structures made up of the calcium carbonate secreted by coralline red algae which would freely roll around on the sea floor: Hundreds of Texigryphaea roemeri (Gryphaeidae) oysters: The layers above the micromorph zone abound with more typical Grayson Formation lithology & fauna, such as this Mariella rhacioformis (Turrilitidae) ammonite fragment. This species occurs in abundance in at the site in the more typical layers and occasionally as limonitic/pyritic micromorphs too: A portion of a typical non-dwarfed Mariella bosquensis (Turrilitidae) ammonite: Protocardia texana (Cardiidae) clam:

Hi there! I saw a fossil at an antique show recently marked as a Geocoma carinata and was wondering if it was real or fake; it looks almost too good to be true, and I would really appreciate some expert input!

I found this in Kansas and I am wondering which fossil it is. At the same place I found pyritized pieces that would also go with these fossils ( the end part that looks like a screw) Also would like to know what the white thing is in the second photo.

Hi, I’m newer to collecting fossils and I was just wondering if these two brittlestar fossils are real or not. The information I have on them are as follows: Ophioderma elegans,from the Jurassic; Calovian of La haute vault, Ardeche, France.

I got this fossil today. But it looks a little bit suspicious to me. Especially the color and the light yellow tips of the brittle star. Can you please have a look for me? Thanks.

I have never seen starfish and matrix like this. Do you think it is real or fake? Thanks in advance!

I am very interested in purchasing this brittle star from Dorset, UK. It is not cheap. so just want to ask your opinion ☺️ do you think it is 100% natural and real? Thanks!

Can I have some help in ID for the 4 brittle star fossils I have? Do you think they belong to same sub species or different ? They are all from Morocco. Thank you so much!

Dear friends, I am very new to fossil collections and know little things about fossils. The brittle star fossils attached below are my first collection. I love brittle stars and I got it from a local seller in Australia. I would like to have your opinion on these two fossils. Are they authentic? If they are, where are they from (I only know they are from morroco), but not sure which part. Thanks!

Hi all, I have a particular request. I want to trade for a starfish or brittlestar I can trade one of the following two fossils: Predaceous diving beetle larva Coptoclava longipoda 125.5 - 122.5 mya | early Cretaceous Yixian Formation Liutiaogou Village, Dashuangmiao Town, Ningcheng County, Nei Mongol There are several additional insects as seen in the pictures below Black ammonite Trachyceras multituberculatum 232 - 221.5 mya | late Triassic Xiaowa Formation Lower Member, upper unit Guanling, Guizhou Province Matrix is 65 mm long Thank you - Andy

You already read the title so lets start: (all of these were bought) Brittlestar? No idea what species this could be. Fossil shrimp, possibly carponanus? Fossil fish found behind shrimp fossil. possibly Knightia? Fossil leaf. again no idea what this type of leaf.

I picked up this Brittlestar recently at a fossil fair, but when I tried to research it later the Cyphaspis label seems to refer to a Trilobite sp. Can anyone clarify what I have here?

Here's a brief description of how I prepped the Yorkshire coast Palaeocoma milleri that won last month's invertebrate competition. It was found in the middle of the top face of large, hard sandstone boulder. The tide was coming in quite fast and I wasn't sure if it was extractable in time - but after a frantic hour of chiseling a channel around it it was ready to lift. Always a scary moment but the Estwing bolster did the job . The resulting block is 12" x 8" x 3". The curly arm on the left was loose and broken into four pieces - these were carefully packed and glued back on at home. The next step was to rough it out with an air pen and abrader to see how far the arms went. Sadly, none of the others were as complete as the exposed one but that's often the way with brittlestars... Also, the surface of the central area is slightly corroded by the acid from a decomposing thin layer of pyrite - a common problem from this formation. I also used some potassium hydroxide flakes which is why the matrix has turned red-brown along the top arms. Then more work with pen and KOH to expose the centre disc and bring out the arms: It was then soaked for a couple of days to remove KOH. After more penning and tidying with the air abrader, the pen marks were ground away and that's as far as I've taken it - there's certainly scope to do more but I'm leaving it for now.

I entered this specimen in the fossil of the month for July and it lost but I found out today that its a much bigger winner with distinction. I posted photos of the Brittle Star on my facebook page and was informed that a Dr. Fred Hotchkiss of the marine paleobiological research institute might be able to help in identification. I sent him photos and he got back to me and said "As far as I am aware, it is a new record for this formation and locality". He went on to say that "Furcaster has a fairly extensive fossil record from Ordovician to Permian on several continents, but yours is a first for the NY Devonian". I never found a first for New York before! I also found out from George McIntosh of the Rochester Museum and Science Center that the crinoid on the plate isnt a Logocrinus and he refused to speculate. After a long examination under the microscope and a lot of hmmms and huhs, he couldnt ID it. Thats also a first for me, to stump George on a Crinoid ID. I have posted before about this specimen on the FF, but wanted to share in the latest update about it. mikey
