  1. Is there something fishy here?

    Hi TFF friends, Here is one of my recent find. Hunting report to follow. I would like to get your help on this fossil. It looks like a bone and looks like fish to me but as it is the first time I found such fossil, some help would be welcome. It is a little bit smaller than 3 mm and broke right in the middle when I broke open a boulder on the shore. It is Cenomanian of age, and was found in Amakusa, Japan. Thanks by advance, David
  2. Mukawa-ryu documentary

    Here is the english version of the japanese documentary made for the Mukawa-ryu discovery. It was aired a year ago but it is still an interesting documentary about the most complete japanese dinosaur ever found.
  3. Few month ago, an ammonite hunter from Hokkaido came to Mifune Dinosaur Museum in kumamoto prefecture to exhibit part of his collection. I had the occasion to take picture of his collection and as I promised on an other thread to put some picture of it, I created this post. I hope you will enjoy the pictures.

  5. Added three new teeth in recent times to my collection of exotic meg teeth, I'd like to share since there,s not to many images from these localities out there, the photos maybe in shabby quality because I pulled them directly from my Instagram page to save time. 1) This partial tip of a meg was found in the Chiba prefecture of Japan! Acquiring this, even just a fragment was a real pain in the butt as megs from Japan are extremely scare. 2) Even though its not a Meg of course but still being the closest ancestor, this 3.1inch chubutensis tooth was found at a land site in Lecce, Italy with gorgeous color! 3) This tooth measuring 4.1 inches came from new site in Bangkalan City, Java, Indonesia. A majority of the megs here were found with absolutely terrible preservation so this one is one of the best out of the bunch! A few more pics of these teeth can be found on their posts on my page at https://www.instagram.com/nyislandfossils/ if its ok to post this here.
  6. What is that thing?

    Good evening TFF friends. I have found the following fossil few time ago in amakusa, japan. It is a cretaceous formation (santonian) called himenoura formation. It is a small round fossil of only 2 to 3mm. It has a conical shape with kind of regular growth circle. On the picture you cannot see it but it is covered with enamel. It is kind of common fossil in the part of the formation where cretalamna' s tooth are abundant. Could it be a kind of dermal dentical or is it something else? Thank you very much for your help. David From above. There is still some matrix on the upper part but the fossil is perfectly round.
  7. A new cetacean-related paper is available online: Tsai et. al., 2017. Northern pygmy right whales highlight Quaternary marine mammal exchange. Current Biology 27 (19):R1058-R1059. (link at http://www.cell.com/current-biology/fulltext/S0960-9822(17)31096-5) The discovery of neobalaenid fossils from marine deposits in Japan and Italy not only fills a small gap between Miocaperea and the extant pygmy right whale, it also shows that pygmy right whales were widespread in all oceans and seas in pre-Holocene times, suggesting that a number of fragmentary taxa formerly classified in Cetotheriidae from the North Sea basin might be related to the pygmy right whale.

  11. Fossil Site Recs in Japan?

    Hi, I'm super casual about fossil hunting - I'll do it when I get the chance and enjoy it but I'm afraid it's not my life's passion (yet) My usual haunts are Walton-on-the-Naze and other nearby sites, the kind you can wander about and either pick up fragments or break rocks without too much extra equipment. And now I'm in Japan. I've come to Iwate, a prefecture on the northern end of the main island, and will be living here for a while. So how can I find out what sites are near me, and does anyone know the area or have any recommendations? Google is turning up sites that are either museum-only, commercially excavated and private areas, or a fossil park on a different island at the other end of the country.

  15. Japan Fossil Show

    I was wondering if anyone has ever been to a fossil show in Japan. I found some pictures on the Internet of some fossil shows in Japan and the quality of the dinosaur fossils shown are incredible. I'm not sure when or where these pictures were taken.
  16. Ninja !!!

    Few month ago, incapacitated by a broken metatarsal bone, I listened to all Royal Tyrrell Museum's speaker series on youtube when I found among all these amazing an interesting lecture about subject mass extinction event. I can't remember the name of the speaker but during his lecture, he spoke about non-avian dinosaurs' extinction like celestial body, illness, volcanic activities, ninjas who timeslipped to Cretaceous and slaughtered all dinosaurs. I have to admit that the ninja theory really upsetted me.I thaught to myself "Why didn't we hear about this theory more often?" So as I want to help science, and solve this mystery I decided to investigate. Couldn't be better place to investigate ninjas than Japan right? So yesterday I prepared my gear, ate sushis and went to Kumamoto's Tsumori formation, looking for proof... and well, I found some... I only spend one hour on the crime scene when I found one of the deadly weapon japanese ninja used to use: 菱の実 or in shakespeare's language water caltrop. That's right, ninjas used on our beloved ancient creatures this vicious weapon. they used the technic called "makibishi", the same technic that all Samourai feared and that ruined so much waraji (japanese sandal made of straw rope and used during feudal era). I found fossilized water caltrope/ water chestnuts. On a more serious note, I went to the Tsumori formation in Kumamoto yesterday. It is a middle pleistocene formation which yield mainly water caltropes and insects ( the place was a giant pond back then). I didn't find very exciting things but as I didn't post any hunt report for a while I decided to write this one on an humouristic tone and to present you.. well some japanese culture aspects. So except, the ninja time traveler, everything is true. Sorry folks, ninja didn't slaughtered dinosaurs. As during feudal japan almost all samourai weared straw rope sandals,Trapa's seed pods were dried and used by ninja during their escape to slow down ennemies. My finds of the day are Trapa sp. seed pod and leaves, piece of wood indet. with strange features. Hope it entertained you a little bit. See you, David.
  17. Santonian fish scale

    Hi TFF friends, how are you doing? I found last week in one of my drawer those two fish scales I found about a year ago in Amakusa, Himenoura lower formation, Japan. I searched on internet for documentation speaking about fish material found in this formation to get some hint and put a name on those scale but I was unsuccessful. Is anybody has an idea of what kind of fish it could be? And I have another question related to this. As I don't want to die idot, do you have any book suggestion concerning this subject? Thank you by advance, best regards
  18. Santonian Bivalve ID (probably veneridae)

    Hi everyone, It's been a while. Here are two picture of a bivalve I found in Himenoura formation Japan. I have been hunting these place regularly for 2 years but it is the first time I found such large bivale there. I looked into my local documentation to put a name on it but I didn't found anything. Here is some information about the beast: Formation: Himenoura Age: late Cretaceous, santonian size: 13cm long / 9cm width I think it is a kind of veneridae because the hinge teeth (even if difficult to see on the picture and worn) looks like Mercenaria mercenaria teeth. If someone have any idea about the clam shell, I would be gratefull to hear about.
  19. Mifune Dinosaur Museum

    Mifune Dinosaur Museum is a small museum by its size but not by its collection. This natural museum is focused on the cretaceous period and fossils excavated in Mifune area. Situated in the Kumamoto prefecture in the southern japanese big island called Kyushu, Mifune benefits of a formation called Mifune formation rich in brackish water fossils (invertebrates) in its lower part and in dinosaurs and other vertebrates in the upper part of the formation. Mifune has a good reputation among japanese paleontologists since the first carnivorous teeth was found in 1979. Since then, various species of dinosaurs have been found here (Tyranosaurid, Ankylosaurid, Hadrosaurid, Dromaesaurid, Therizinosaurid, ornitomimosaurid). Beside dinosaurs, mammals (Sorlestes mifunensis), large variety of turtles (slightly different from the turtles found at the same period in Asia) and crocodiles (Eusuchia only) were found. In addition to the museum visit, outside activities such as fossil hunting, geological tour are available.

  21. Before starting my hunt report, I just would like to make a short preamble, if you only want to read the report, skip this post and go to the second one. I hesitated a lot concerning this post but I think it could answer a lot of question concerning my vacance (sorry Ash, was cut during our chat by nasty tremors but nice pictures and congratulation!). As few know, I live in South of Japan in a city called Kumamoto. I don’t know if outside Japan the event was fairly broadcast (maybe in Montana’s news as Montana and Kumamoto are twin state) but on month ago on April the 14th, an earthquake (Magnitude 6.5 / shindo 7) hit severely the prefecture at 9:26pm. What we thought to be an isolated earthquake was in fact follow by tremors, little brother (Magnitude 6.4 / shindo 6) and the day after at 1 am by big daddy (Magnitude 7.3 /Shindo 7). Since then we experience afterquake every day. Between the 14th and May the 11th the earth shaked 368 times (only tremors above shindo 3) and 1400 times (all tremors) ‘till today. What’s shindo scale ? it is a scale used in Japan which measure the intensity of an earthquake. The scale goes from 1 to 7, 7 being the most intense and effect on human and infrastructure are described as follow: 1 : Felt by only some people indoors./ Upper sections of multi-story buildings may feel the earthquake. 2: Felt by many to most people indoors. Some people awake./ No buildings receive damage./ Homes and apartment buildings will shake, but will receive no damage. 3: Felt by most to all people indoors. Some people are frightened./ Buildings may receive slight damage if not earthquake-resistant. None to very light damage to earthquake-resistant and normal buildings./ Houses may shake strongly. Less earthquake-resistant houses can receive slight damage. 4: Many people are frightened. Some people try to escape from danger. Most sleeping people awake./ Less earthquake-resistant homes can suffer slight damage. Most homes shake strongly and small cracks may appear. The entirety of apartment buildings will shake./ Other buildings can receive slight damage. Earthquake-resistant structures will survive, most likely without damage. 5 lower: Most people try to escape from danger by running outside. Some people find it difficult to move./ Less earthquake-resistant homes and apartments suffer damage to walls and pillars./ Cracks are formed in walls of less earthquake-resistant buildings. Normal and earthquake resistant structures receive slight damage. 5 upper: Many people are considerably frightened and find it difficult to move./ Less earthquake-resistant homes and apartments suffer heavy/significant damage to walls and pillars and can lean./ Medium to large cracks are formed in walls. Crossbeams and pillars of less earthquake-resistant buildings and even highly earthquake-resistant buildings also have cracks. 6 lower: Difficult to keep standing./ Less earthquake-resistant houses collapse and even walls and pillars of other homes are damaged. Apartment buildings can collapse by floors falling down onto each other./ Less earthquake-resistant buildings easily receive heavy damage and may be destroyed. Even highly earthquake-resistant buildings have large cracks in walls and will be moderately damaged, at least. In some buildings, wall tiles and windowpanes are damaged and fall. 6 upper: Impossible to keep standing and to move without crawling./ Less earthquake-resistant houses will collapse or be severely damaged. In some cases, highly earthquake-resistant residences are heavily damaged. Multi-story apartment buildings will fall down partially or completely./ Many walls collapse, or at least are severely damaged. Some less earthquake-resistant buildings collapse. Even highly earthquake-resistant buildings suffer severe damage. 7: Thrown by the shaking and impossible to move at will./ Most or all residences collapse or receive severe damage, no matter how earthquake-resistant they are./ Most or all buildings (even earthquake-resistant ones) suffer severe damage. 90 % of the houses in the little town where the epicenter of the earthquake was, were destroyed, Kumamoto castle is no more and I could continue for days. A simple search on Google will provide you more picture than you want to see. The earthquake happened at the section between 2 fault called Hinagu fault and futagawa fault at a depth of 10 Km. The prefecture is now a paradise for Japanese geologist as new fault were created and because the two side of hinagu fault slide in different direction on 2 meter. Besides the earthquake we entered few weeks ago in the monsoon season and as land is weakened by earthquake it provoked a lot of land slide. This situation caused me to be silent on the forum and forced me to stop fossil hunting for weeks until last week. Was a little bit tired mentally so I needed to get some fresh air and to think about everything but earthquake so I went to my 2 preferred spot on the 13 and tested my chance. The post that follow is my hunting report.
  22. Hi, just a recap of my situation: I live in south of Japan in a city called Kumamoto and I prospect mainly for fossil shell the Himenoura formation which is an upper cretaceous (santonian) marine deposit formation. Even if I know that a lot of shark teeth were found at my usual spot, I never looked for it until my Super Secret Santa send me some superb cosmopolitodus Hastalli tooth and I caught shark tooth virus. Since then, I looked more carefully to this little beauty and found some. As my knowledge in shark tooth is still pretty limited, I ask to a japanese friend of mine who's more into teeth and who told me that the tooth I found was lamna's one. here is the picture of my the one I found. however I have some question about these tooth. As I was looking for information concerning cretalamna in order to determine the place of the tooth I noticed that all cretalamna tooth had cusp. Like this picture from an old post: http://www.thefossilforum.com/uploads/monthly_07_2015/post-3940-0-35234500-1436898635.jpg Did I misidentified the tooth or is there some cretalamna sub species which would have tooth without cusps ? Thank you very much for your help and I hope taht this post will help for futur lamna's teeth identification. David
  23. Hi, Let me tell you about the best week-end I ever spend as fossil passionate. Saturday: Everything started Saturday (27th) at the Mifune Dinosaur Museum (MDM) where I help there as volunteer about three times a week. I am usually in charge of the child related event like post card or replica work-shop however this Saturday was not a usual Saturday. It was the day (MDM) have to send back to Montana’s Rockies museum the 1,5 Ton of rocks and fossils they received 1 years ago when started the “preparation project” and it was the day before the symposium and coming of Phillip Currie in Mifune. In fact MDM and Museum of the Rockies are sister Museum since 2012 and established a program with MDM. According to this program, MoR send to Japan bones to prep, and prepped bones are send back the following years. Last years, MDM received about 1,5T (resin+matrix) and extracted about 140 Daspletosaurus’ bones. For the occasion, Patrick Leiggi and Carrie Ancell came to Japan to supervise and help for the final preparation. For an amateur like me, seeing these professionals working and the result of this years of work was incredible. So after a hard day helping for the preparation for Mr Currie arrival and the sending of the Daspletosaurus’ bones I came back home with the promise than Monday will be a wonderful day. And what wonderful day it will be!
  24. After 2 weeks of cold weather, today, Winter seamed to take a break. No clouds, sunny weather and temperatures above 18 degree celsius, I didn't have to think twice, let's go to the adventure ! As some of you have already noticed, I am more a seaside fossil hunter and today would have been a perfect day to make my skin's tone perfect if the tide would fit my schedule. Too bad for me, low tide time was a little bit too late for me so I decided to drive to Mifune's mountain. Mifune surrounding mountain are part of the Mifune formation. The formation age is Cretaceous (Turonian) and divided in two different Fauna. The lower part of the formation is mainly composed of marine fossil like bivalve but also turtle bones, shark teeth... The upper part of the formation is composed mainly of continental fauna and dinosaurs bones are often found. I divided my trip in two part: 1-Morning: Yoshimuta Plateau (Mifune Lower formation) I went there few times and wanted to explore the surrounding to see if I was able to find some nice spots and bivalves. 2-After lunch: Dinosaur hunt! First time I really took time to look at a geologic map and looked for bones. Yoshimuta: I arrived at about 10:30am at the entrance of the trail and had a 1 hour walk in the mountain before finding and interesting spot. A kind of road cut in the mountain. By looking closer I immediately i noticed: Cerithium Pyramidaeformis, good sign there was life here millions years ago. Now it is time to dig a little bit a see what treasures will appear. Matrix was hard as heck but, I found enough nice bivalve to put a big smile on my face for the day. Put all my found I my Back pack, ate a Rice ball and returned to the car for a 30 minute ride to the next spot and who knows, maybe Dinosaurs. 2- Yakata River I drove to Yakata river and Amakimi Dam. I noticed that part of the river dried up and where surrounded by the upper part of the Mifune formation. If Dinosaurs there are, I thought I would have a chance to find somethink there. I parked my car next to the dam and was welcomed by this sign Temperatures are still cold so I think there is nothing to fear but for someone who is afraid of snakes like me, this sign had a big effect. A picture of the dried up river bed : I tried to go down to the river bed but my adventure in Dinoland had to stop here. As I thought, there is dino bones in there unfortunately the area is forbidden and special clearance was requested to dig up fossil there. I didn't have the occasion to dig up dino bones but I still found a spot where bones are. so good experience for me.

  25. Hi, because our passion is not only about rocks and is made at 50% by trips, discoveries, and people I will post here pictures of my hunting spots, japanese panorama, people, place which made my fossil hunting trips particular, memorable and enriched me as much as fossils do. I hope you will enjoy this thread and that you will be able to have an insight of my Japan.
