Hi TFF friends, Just to show you my latest find. Himenoura lower formation Late cretaceous, santonian Amakusa, japan Height: 9mm I think it might be an Enchodus tooth. There are occurrences of Enchodus sp. from the scientific litterature and saw some of the fossils, however as those teeth are poorly preserved, I am not sure at 100%. It has one notch like structure at the apex, one carina on the proximal edge with very well preserved serrations from the apex to the base of the tooth. The distal edge is round. Fine striations are running all over the crown from the base to the apex.

This unusual Brachiopod is Leptodus nobilis. During the Permian there were many examples of 'experimental' Brachiopod genera. This genus, in life, had a greatly reduced valve which exposed the brachidium which supported the lophophore, and so we see the inner workings of this animal. In the picture are two specimens, each about 6cm. X 3cm. They are from the Lower Kamiyase Formation, Kesen-numa City, Honshu, Japan. Quite rare fossils, I think.

I don't think anyone has posted about this museum, but the Tokai University Museum of Natural History is a local museum near my family's hometown in Shimizu, Shizuoka, Japan. This is a museum that I visited a lot of a kid, but I was told that the museum as well as the aquarium here was going to close to the public sometime around March of this year? Haven't been here in like 15 years, so I figured I should go one last time before it closes down. You can also get a discount for tickets at convenience stores. It's not a huge museum, but there was some oddities. Also, some of the labels here are either outdated, or . . . a bit odd. Cetiosaurus statue Species: Pterichthyodes milleri and Pterichthys milleri Locale: Scotland, United Kingdom These are the same exact thing right? It's clear the labels for these were printed at different times. Species: Pleuracanthus sp. Locale: Germany Species: Scutosaurus karpinskii, Dicynodon amahtyku, Inostrancevia alezandri, Estemmenosuchus uralensis Casts from Russia. Species: Sauropoda indet. (?) Locale: Alberta, Canada (???) They refer to is as possibly being Apatosaurus but . . . You used to be able to touch this fossil, which is what that covered up section in on the information. Not sure if this is pandemic related, or they figured it wasn't a great idea somewhere down the line. Species: Tarbosaurus baatar (Cast) Locale: Gobi Desert, Mongolia Original in Russia, which likely explains all the specimens after this one that aren't casts. Oospecies: Protoceratopsidovum fluxuosum Locale: Gobi Desert, Mongolia Species: Protoceratops sp. Locale: Gobi Desert, Mongolia Species: Gallimimus sp. Locale: Gobi Desert, Mongolia Species: Protoceratops sp. and Psittacosaurus sp. Locale: Gobi Desert, Mongolia Species: Deinodon tidoe (???) Locale: カプサイ (Kapusai?), Russia Good old Deinodon. Age is listed as 97-65 MYA. Not sure where Kapusai, Capsai, Capusai is. Everything about the label looks like a mess, but probably the most interesting piece I saw. I spent the longest time just looking at this specimen. I'm sure as a kid, I just walked right past it to look at all the big skeletons. But coming back here as a collector made me see this place in a new perspective. Species: Tarbosaurus baatar Locale: Gobi Desert, Mongolia Species: Saurolophus angustirostris Locale: Gobi Desert, Mongolia Species: Arcuaeogeryon peruvianus Locale: Uruguay Nothing comes up for this species or genus other than this specific specimen, so it's probably way outdated or was not right from the start. Or it is a spelling mistake. I know a lot of obscure genera don't come up if you mess up even a single letter. Species: Coelacanthus banffensis Locale: Canada Species: Carcharocles Otodus megalodon Locale: Atacama Desert, Chili Species: Carcharodon carcharias (Great White Shark) Locale: Kakegawa, Shizuoka, Japan

I have tried to buy fossils from japanese sites online but everytime they come back and say the product is prohibited from international shipping due to the fossil being considered a 'living' animal so cant be shipped despite being dead for millions of years? Has anyone else experienced this? Also has anyone here successfully bought fossils from japan?

Hello everyone! I'm a 28 year old woman from Poland, living in Japan. Long term fascination with anything prehistoric, however a complete noob when it comes to fossils. Hence why I'm here I just got my first fossil (spinosaurus tooth) and already asked about its quality here. So happy I found this amazing forum. Glad to learn from your collective wealth of knowledge. You guys rock! (pun intended)

Muramotoceras ammonite resto?
Mochaccino posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I came across this Muramotoceras ezoenze (yezoense?) ammonite from Yubari, Japan, and was wondering if it seems legit and natural without restoration/reconstruction/tampering? The whole piece is about 6cm at its widest. I can't accurately assess the quality of preservation/prep, but to me the appearance seems consistent with other specimens, except that this one seems incompletely prepped. For the same reason I don't think there is going to be much tampering with parts still embedded in rock but I am no expert. The seller isn't completely sure, but thinks there is no tampering other than the matrix being cut flat for display purposes. If it helps, I am waiting on some extra close-up photos of inner whorls, and maybe some photos with UV. Any thoughts? Thank you.- 7 replies

Hi TFF friends, Last time I went fossil hunting I found this pretty beaten shark tooth on the surface of a rock lying on the beach. Himenoura formation, Late cretaceous, -85MYA Kumamoto japan. The apex is missing but it is none the less an interesting tooth. At first I thought it was my first Squalicorax tooth but when I looked under magnification I was not able to see any serrations and noticed a nutrient groove and a small cusplet here on the left side of the root in the photo below. After extracting completely the tooth from the rock at home, I discovered a lot of folds at the base of the crown. The tooth is 100mm wide for 50mm high. Even though this tooth size is quite bigger than the tooth I found, I am now thinking it could be a Protolamna sp. Posterior tooth. In the past, I found from the same location a Protolamna sp. anterior tooth (30mm wide for 40mm high), and this genus is also mentionned in the literature. What do you think? From above with nutrient groove visible What looks like a cusplet

Kuji Amber (Tamagawa Fm., ~91.05-85.2 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
“Kuji Amber” Hirono, Iwate Prefecture, Japan Tamagawa Fm. (Kuji Group) ~91.05-85.2 Ma Total Weight: 1.3g Longest Specimen: 10mm Lighting: Longwave UV Entry five of ten, detailing various rare ambers from European, Asian, and North American localities. Studies on this amber, and Japanese ambers in general, are especially fascinating from a pharmaceutical point of view. In early 2012, a particular diterpenoid was extracted from Kuji amber that has been shown to possess powerful anti-allergenic properties; this compound was named “kujigamberol”, and is extracted from powdered amber using methylene hydroxide (MeOH). In the case of powdered Iwaki amber, 18.5g of amber was added to MeOH for 3 days, after which the MeOH was evaporated leaving 0.8g of solid extract; further extractions and purification were applied, leaving 1.0mg of a colorless oil. Kujigamberol can be obtained from Kuji, Iwaki, Choshi, Mizunami, and Ube ambers, but its concentration decreases proportionally to the ambers’ age (i.e., the older the amber, the lower the yield). Kuji amber is found in exposures along the inner southern half of Kuji Bay, as well as further south at Noda Bay along the coastline, just north of the mouth of the Akka River: the exposures consist of sandstones, conglomerates, and amber-bearing carbonaceous mudstone (which also contains small plant fossils); the Tamagawa Fm. is roughly 200m thick, and amber is found within the middle and upper portions. Shell fragments of freshwater turtles can also be found in a bone bed within the uppermost portion of the Formation; immediately above the bone bed is a layer of volcanic ash containing zircon grains: these have been dated to be 91 million years old. The amber of the Kuji and Noda Bays is often found washed onto the shoreline as waterworn grains; there is a more well-known deposit inland, however, where amber is mined directly from the earth.

Hinoshima formation, Cretaceous (Santonian), Japan
David in Japan posted a topic in Fossil Hunting Trips
2 weeks ago, I surface hunted fossils at my favorite spot in Kumamoto Prefecture, Japan. It was a very hot day of November and as I was alone and had plenty of time, I have been able to return to several spots (same formation though) I do not often go to. As usual, as the places I went are part of a national park, you are not allowed to take fossils directly from the formation however you can still take back rocks that felt from the cliff or which lies on the beach. I first stopped at Kojima's camp site. Kojima is a very small island (the name Kojima means small island in Japanese) that was transformed in a small camp site. Before being transformed into a touristic spot, the place yielded lots of late cretaceous sharks teeth and heteromorphs ammonite unfortunately, the rich fossil layers has been covered in concrete and it is hard now to find teeth there. I walked around the island and despite the fact I didn’t find any tooth, I found a bunch of Inoceramus (Platyceramus) higoensis and fossils of Sea Urchins however I wasn’t as lucky as my new little friend as didn’t bring anything back from from this specific location.- 8 replies

Hi TFF friends, it's been a while. I hope you're all fine. This week, I explored my favorite place in Kumamoto prefecture (trip report coming these week-end) and found the following fossil. First time I saw such fossil from this location. I have browsed the literature related to this location but I unfortunately didn't find any clues about what this fossil could be. I suspect this could be some kind of fish tooth. In the all the papers I read about this location, I found some mentions of fish material found there but no description or further information. I was wondering if this could be some kind of Pycnodont tooth, the general shape matches and we can see in cross section the kind of fold where the root is missing. However the regular grooves on the surface makes me doubt about my guess a little bit as I think that Pycnodont tooth are "smooth" . If any one has a guess about what it could be, do not hesitate to throw it in the comments. Any help is welcome. Size: 8mm by 3mm Himenoura Formation (lower) Late Cretaceous (Santonian) Kumamoto prefecture, Japan

Dear TFF friends, It's been a while since I visited our fossil lovers community. I hope you're all doing well. Few months ago, I went to my favorite late cretaceous spot in Japan. Himenoura formation is a marine formation from the late Cretaceous (Santonian) where ammonites, bivalves, shark teeth, and crustaceans can be found. Last time I went there, I found the following fossil. In is quite small, and at first glance I thought it was some kind of bone fragment or small tooth's enamel negative but after observing it under microscope, I was able to see that it was multiple fragments (some still inside the matrix) of a quite thin "kind of bone" with this kind of hexagonal pattern on the outside (cf photo) and vertical columns in cross section (wasn't able to take picture, will post pictures as soon as I can). I may have an idea of what it could be (possible shark cartilage?) but I would like to hear your opinion about that fossil. Thanks by advance, David

I saw this fossil for sale in Colorado labeled as a Archaeopteryx (second picture) by it it looks nothing like an Archaeopteryx. I google image searched the picture and the only look alike was on a website for Japanese travel photos (first picture) and I believe it was at a dinosaur museum in Japan. I'll put both pictures below! Please help me identify

Hello, I see these shark teeth from an auction. I don't know if they are fossilized or come from a recent animal. Unfortunately the photos are not very good. I still wonder what kind of shark these teeth could have come from. My first idea was Megamouth shark, but teeth of these are of course very rare. On the other hand, it might fit because the teeth are found on Japan's coast and Megamouth sharks are also found there (if there are recent species). Can you help me with the ID? I'm really not quite sure, I've never seen teeth like this before. Thank you and best regards from Germany.

Hello Fossil Friends, Saw this in the news today so thought I’d share: ******************** World's smallest dinosaur egg fossil discovered in Japan Source Link A team of researchers said Tuesday it has discovered the world's smallest dinosaur egg fossil, measuring about 4.5 centimeters by 2 cm, in western Japan. The fossil of the egg, estimated to have weighed only about 10 grams more than 100 million years ago, was found in a stratum dating back to the Early Cretaceous period in Tamba, Hyogo Prefecture, according to the team. Supplied photo shows the world's smallest dinosaur egg fossil found in Tamba, Hyogo Prefecture, western Japan. (Photo courtesy of the University of Tsukuba and the Museum of Nature and Human Activities, Hyogo)(Kyodo) The researchers at the University of Tsukuba and the Museum of Nature and Human Activities, Hyogo, among others, who have analyzed the fossil, said it likely belonged to a non-avian small theropod. Skeletal remains of small dinosaurs are far less common than those of large dinosaurs, such as the Tyrannosaurus, which was also a theropod, and Kohei Tanaka of the University of Tsukuba, a member of the team, said he hopes the discovery will "help shed light on how small dinosaurs reproduced and nested." The team surveyed the stratum, which dates back 110 million years, between 2015 and 2019 and found four fossil eggs and over 1,300 scattered eggshell fragments. It has confirmed the findings, including the newly discovered one, which has been named Himeoolithus murakamii, can be categorized into four different types. The team said the discovery suggests that various small dinosaurs were nesting together in the area, known as one of the world's richest Lower Cretaceous fossil egg sites. Fossilized dinosaur eggs have been found elsewhere, including Spain and Mongolia, but many of them are 5 to 7 cm in length and weigh about 30 g. ******************** Thanks, Robert
