Generally, the genus is assigned to the family Amphilemuridae, which according to some researchers is more closely related to today's hedgehogs (Erinaceidae). According to other studies, a closer relationship to the elephant shrews (family Macroscelididae) is also considered for the family. Taxonomy according to Fossilworks. Diagnosis for Pholidocercus hassiacus von Königswald & Storch 1983 (translated from German by oilshale): “A stout, ground-dwelling animal of a good 35 cm total length (head trunk just under 20 cm, tail a good 15 cm). In biological adaptation type, it is comparable to recent hair urchins (Echinosoricinae). Scaly dermal ossifications in the tail region; long bristly dorsal hair; probably possession of a horny plate over the forehead, the extension of which is indicated by deep vascular grooves on the skull roof; split terminal phalanges. I1/, C1/ and the persistent dP/1 relatively enlarged: C/1 premolariform; P/4 with dominant inflated protoconid, very small metaconid, and short broad talonid process; paraconulus and metaconulus of upper molars not connected by shelves to their respective outer styli, and paraconulus not connected to paraconid; lophid-shaped paraconid of lower molars reaches approximately lingual margin of teeth; hypoconulid of lower molars reaches approximately lingual margin of teeth; hypoconulid of lower molars located approximately median and somewhat prominent distally. See also emended family diagnosis.” Identified by von Königswald and Storch 1983 (this is one of the paratypes in their publication). In 1978, the Senckenberg Museum in Frankfurt organized a special exhibition "Fossils from the Messel Pit". The same fossil was in many exhibits that the museum had which included fossils borrowed from other amateur collectors.

This piece of arkosic sandstone from the late Eocene Coldwater formation north of Santa Paula, CA, has a few marine species traces. It would be great if anyone could ID the bivalves, but what really seems different is the set of chevrons I've pointed to in the top photo. Maybe it's just two bivalves wedged together to look like one? Appreciate the help!

Hi guys hope everyone’s having a great Easter, if you celebrate it. A few days ago I got to go fossil hunting for the first time in monthswhile it wasn’t the most productive as the beds were covered by sand and not much erosion had taken place but I found enough in some micro matrix I bought home to warrant a trip report The geology of bracklesham bay To the left, the yellow is wittering fm. Some fossils can be found here but not many. The best area to hunt is the green earnley fm. Which produces the most abundant fossils, here is a photo of it when exposed the fossils to clay ratio averages out at about 3:1 in some beds! on this hunt, the area I focused on was the E5 palate bed, but I found a lot from the turitella bed and the nummulites bed to the right, is the marsh farm fm, this is good for finding fossil corals, such as this anyway, a good source of info is this great video on YouTube, where I got a lot of this info from for identification of fossils, I like to use this website http://dmap.co.uk/fossils/bracklesham/vert/brackvert.htm There are some great specimens to check out on there, but not all species at bracklesham bay are listed there we set out at 3 in the afternoon to be at the beach 2 hours before the 6:30 low tide, at bracklesham the best hunt is on the falling tide. It was a glorious day, not a cloud in the sky, when we got there, we even went in the sea! Not for long though, as we all would get frostbite. Soon the hunt began. here are some pics of the site and me not much was found in the first hour and a half, only a few small ray bars, the most common vertebrate find here, and this luck would sadly continue, it was a very poor day for hunting sadly, I was the only one on the beach that day out of 4 others that came out with anything other than shells, sad considering on a good day you can walk out with 50-100 vertebrate bits, at bracklesham you are at the mercy of nature I guess After an hour of little luck, I found something that made my day, a very rare bone, anything other than sharks and ray is very hard to come across here, in my time collecting here; I’ve seen 3 people walk off with an auriculatis but only 1 other with a complete bone like this, so I’m super happy it has been identified as trionyx marginatus. after half an hour more of not finding anything, I went to collecting matrix as I wasn’t finding much. I have run out of time to post now so I will put the rest of my finds up later today

Hi guys, found this in the lutetian earnley formation of Bracklesham bay today and i was wondering if anyone could help me identify it, as bones like this are rare and i havent had any experience identifying them. I find turtle phalange the most likely but crocodilian or even mammalian is a possibility thanks for your help I must add, sorry for the awful photography, my lamp is broken so i needed to use flash

Hello guys. I have found this collection of specimens on the matrix on the eocene era site near city of Vrgorac, Republic of Croatia. In my humble opinion, it is quite interesting, considering the number of different species included. In other words, there is really a lot going on So far, I have only identified some kind of solitary coral (picture 2 and 3) and several species of nummulites (pictures 4,5 and 6). I would greatly appreciate any help with identification of other specimens. Thank you in advance.

Hello together, I just got a package in the mail, that is less fun than fossil hunting outside, but still I like what I see. I got no information on locality or age, but I can assume north africa. It was sold as Basilosaurus neural spine. What I don´t understand is the proximal surface of the left one, it doesn´t look fractured, rather like a complete bone/articulation surface. Also I am not sure if the size is right for Basilosaurus itself. Although I spent some time tinkering with whale anatomy, I have never seen a basilosaurid bone up close, so I am out of my expertise her. Who can help? Scale is in cm/mm Thanks J

I was hunting a site on the Potomac looking for some Eocene and Miocene fossils yesterday. When I got to the site I found this gorgeous snake vertebrae about 15 minutes into my trip, so I knew it was going to be a good day. After that it was slow collecting for the next few hours, I was only picking up a tooth every once in a while despite the incredible conditions. But then, 10 minutes before I was about to leave I stumbled upon my best chubutensis yet at about 2 3/4 in. (or 7 cm) rolling around in the surf. One that I have been dreaming about ever since a starting collecting two years ago. A total trip maker! I hope you enjoy the pics!

Hello guys, As a begginer in the world of fossil hunting, I would appreciate your help with identification of several coral specimens I have found in the eocene era fossil site near the town of Vrgorac, Republic of Croatia. My guess, at least for the first specimen (first 4 photos), is that it represent some kind of Pattalophyllia, whilst for the others I honestly have no idea. Also, the last specimen (last 3 photos), looks like some kind of horn coral, which is weird, considering the fact that they went extinct during Permian and especially because it was found in close proximity of other specimens ( maybe 20-30 meters) and not even a meter form the (possible) Pattalophyllia. Thank you in advance.

Septal ornamentation often refletcs the microstucture of the septum. It can be observed in specimens without special preparation simply by observing them carefully. Upper margin, inner margin, external margin and lateral faces are important details to take into account. Today I'm going to show you some examples of septal lateral faces ornamentation. As always, I hope that it are to the liking and interest of that select group that I have called "coral lovers". Let's start with smooth lateral septal face in an indeterminate solitary coral from de middle Eocene (Bartonian) of South Pyrenean basin. Image of the lateral septum in a broken specimen. Natural transverse section of another specimen We continue with grannulae lateral septal face in Funginellastraea from middle Eocene (Bartonian) of South Pyrenean basin. A well-preserved specimen showing the granules. Detail of the lateral of the septum in another specimen. And finally pennulae lateral septal face in Synastraeidae indet. from middle Eocene (Lutetian) of South Pyrenean basin. Lateral septal face showing pennulae. Upper margin from the same specimen. And longitudinal natural section from other specimen of Leptophyllon barocum Eliasova, 1974, Synastraeidae, middle Eocene (Lutetian) south Pyrenean basin showing tipical section of pennulae.

Asineops (Greek for "donkey-faced") squamifrons was first described by Cope as having an affinity to the pirat perch family. Later, with more detailed study, this species was found to lack the diagnostic characters of that family. Thus it is not yet clearly assignable to order. Although this species is much rarer in the Fossil Lake sediments than in Lake Gosiute deposits, the specimens from Fossil Lake are much larger than those from Lake Gosiute.

My wife found this in some talus. It is 5mm long axis. Image was taken with a G9/Oly 60mm with extension tubes (2x). Is this a Crinoid? Looks like the feeding part. Any Ideas on what this fossils is? Keasey Formation, late Eocene. Mostly Mollusk and Gastropods however Crinoids are listed as being found in this location but rare.

Hi guys. I have found a fossil for whom I presume is a myliobatis palate (medial). It was found in the eocene era site in Croatia, near city of Vrgorac. Thank you in advance.

Hi everyone, I'm trying to id some very small shark teeth for an independent research paper I'm writing and am a little unsure on my ids. I took some photos of some typical specimens and was hoping to get some feedback. The scale bar is mm. I put what I think the species is with each group of photos. Any feedback and tips for differentiating these species would be greatly appreciated.

Got a sweet slab of green river fish today but I’m not sure on what type of fish they are, I’m pretty sure ones a knightia, but could someone give me an ID on the others

I am at a loss with this one. Kind of a crimped texture (reminds me of an empenada edge) on the edge. It most reminds me of an ostreid bivalve, but I'm not used to the invertebrate material at this Monmouth County, New Jersey Eocene/Miocene site having this texture. Could be a tooth of some sort, but nothing like I have seen before. Hopefully the photos are good enough to have a few new ideas added to the mix.

Hi hoping for a bit of help with a couple of shark teeth finds from the Eocene (42mya), Bracklesham group in Whitecliffe Bay on the Isle of Wight. I don't often find shark teeth so not sure about the ID so hope someone on here can help. Walking back to the car I found a vertebra in the sand washed out from the cliff, (cliffs are Bembridge Marls / Solent Group or early Oligocene - about 34mya) my initial thought was turtle but something about the shape is making me think lizard so again would appreciate any help with the ID. (Grid in the photographs is 5mm square). If other views would help please let me know and I will post them as well. Any help would be much appreciated, Cheers Martyn

Hi guys. As a begginer in the world of fossil hunting, I would very much apppreciate your opinion about this specimen. It was found in the eocene era site, near the town of Vrgorac, Republic of Croatia and I presume it is some kind of stromatolite. Thank you in advance.
-
Hello guys. Recently I have posted couple of pictures of possible stromatolites specimen I have found. I visited the same location today and I have found a couple of more specimens which look like some kind of stromatolites. Any help would be appreciated.

Hello! Here are several photos of a fossilized colony of some sort of worm, or so it appears to me. Please excuse the remnants of clear nail polish I used years ago to increase contrast before I knew better. I came across this in Santa Paula canyon about 2 miles northwest of highway 150 where it turns west at Thomas Aquinas College, Santa Paula, CA. It had washed down decades ago from probably a Matilija Formation exposure. The matrix grain seems quite fine and the rock is very heavy. Although I've been up and down the creek countless times, I've never seen the source bed. Eocene oysters, clams and echinoderms have been collected in the canyon. Thanks for your help.

Hi guys, I thought I’d start a thread for what is in my opinion, one of the most under appreciated group of marine vertebrate fossils. Anyway, to provide some info on these ratfish and why I find them so interesting, primarily I am drawn in by their rarity. Unlike sharks, that shed their teeth on a regular basis, these fish have one set for life! Anyway, enough talk, more fossils, I will start with some very uncommon jurassic ones, if anyone has any, please add to the thread

This tooth was collected from one of the Monmouth County, NJ, mixed Miocene/Eocene sites. The curved shape makes me want this to be a Parotodus benedeni, but it could just be a weirdo Odontaspis, Carcharias, or one of the other more common types of sharks. Would love to hear what you all think.
