Well-preserved dinosaur soft tissue fossils have been found. Devastating land slide buried dinosaurs alive and fossilization started soon after their death.

   Numerous dinosaur soft tissues have been found in Mikawa district, Japan. Finding　soft tissue fossils have been believed to be extremely rare, since they are easily decomposed. But I found more than 3000 dinosaur egg and 2000 dung fossils in the same area where soft tissue fossils were found. As long as so many dinosaur egg and dung fossils were found in Mikawa district which is my home town, it is obvious that numerous dinosaurs once lived in this area. Last year, I started finding these peculiar and crucial pebbles, which contain well-preserved fry fossil as shown in the photos. They were fossilized in group. Apparently, they had no chance to flee from the devastating landslide, which took place out of the blue. Now I have the dinosaur fossils such as brains, lungs, skins, guts, testicles, ovaries and the others. Interestingly, these fossils I got are all well-preserved. I infer that several hundreds of dinosaurs also got involved in the disastrous landslide and fossilized quickly before decomposition proceeded. If we fail to recover dinosaur DNA utilizing these fossils, there will be no chance to clone it forever. Lastly, when I see so many egg fossils and herbivore dung fossils shown in the photos below, I imagine affluent dinosaur world. But there were so many egg fossils which hutched every year, herbivorous dinosaurs must have consumed enormous amount of trees they seem to have lived on. I infer that they ate up trees on the mountain slope creating bare land which probably caused the devastating massive landslide occurred sometime in the dinosaur era.

          Numerous dinosaur dung fossils of both herbivore and carnivore have been found in Mikawa district which is my home town, Japan. It’s been said that herbivorous dinosaur dung fossils are extremely rare to found. But it seems I have found a lot of herbivorous dinosaur dung fossils, which looked like balls of fiver. This peculiar feature made me think they are herbivorous dinosaur dung fossils. I also found wood fossils, on which they must have fed. I also have a lot of dinosaur head fossils with bite marks on them. Apparently, they were bitten on the head and eaten by the carnivorous dinosaurs. Dungs from the carnivorous dinosaur are also shown below. When I see those abundant herbivorous dinosaur dung fossils, I imagine the tropical sun shine and thick forest. And carnivorous dinosaurs killed herbivorous dinosaurs by biting their heads. I have so many heads of herbivores. Some of them are so small and bite marks on them are also small. The battles between them were fierce since they were young. They surely lived in a Darwinian jungle. Photos of carnivorous dung fossils are shown below. I discovered lots of well-preserved dinosaur fossils of various kinds.I think the place where I found the fossils is one of the best fossil sites in the world. And lots more will be discovered in the future.

Fossilization process of Testicle

It has been said that soft tissue fossils are extremely rare to find, but it appears I have found numerous soft tissues fossils such as testicles, ovaries, skins and so on, in Mikawa district, Aichi-prefecture, Japan. I also found lots of dinosaur dung and egg fossils in the same place where numerous soft tissues fossils were found. As long as so many dung and egg fossils were found in Mikawa district which is my home town, it is obvious that the dinosaurs once lived in my neighborhood. Though discovery of the testicle fossil has not ever been reported in the world, I found a hundred of them in 3 years of time. Considering the number of the testicle fossils I found, there is a possibility that several hundred dinosaurs were buried alive by a massive landslide or volcanic eruptions, and fossilized quickly before putrefaction process proceeded. 

   Secondly, the photos of fossilized testicles are shown below. I would like to refrain from commenting on them, because a lot of factors may affect the outcome of the fossils. But in the last photos, testicle fossils putrefied a bit are shown. I hope that spermatozoa could be isolated from these fossils for sequencing DNA. I think that Mikawa district is unprecedented and special place and suited for studying the life of dinosaurs.

Soft tissue fossils and DNA sequence

                  Soft Tissue Fossils by M. Yamamoto

It has been reported that soft tissue fossils are extremely rare find because they are easily decomposed or putrefied. But it appears I found numerous dinosaur soft tissue fossils such as testicles, presumably ovaries , developing embryos and the other fossils in Mikawa district, Aichi-prefecture, Japan. And I also found hundreds of dung and egg fossils. As long as so many dung and egg fossils are found in a small area of my vicinity, it is obvious that the dinosaurs once lived in this area of my vicinity. And there is a possibility that several hundreds of dinosaurs were killed at a time, buried quickly and　fossilized before putrefaction process proceeded. All the fossils I found are well preserved and will give us good materials to sequence dino-DNA. Photos are shown below.

At first, an unidentified soft tissue fossil is shown.

Dinosaur Dung Fossil

　　　It has been said that herbivore dinosaur dung fossils are rarer than those of carnivores to find. But it seems I found lots of herbivore dung fossils. Firstly, photos of herbivore dung fossils are shown below. They are like balls of fiver. So I decided they are herbivorous dinosaur dung fossils. I always try to decide what they are by observing their shapes and appearances. I am a medical doctor and an instant fossil hunter. I cannot analyze for calcium phosphate.

This dung contains broken gastrolith in it.

Secondly, photos of carnivorous dinosaur fossils are shown.

　　This dung was evacuated from high place
and a dent  was made on landing.

These dungs were in the intestine at the time of their death. The intestine was fossilized before they went rotten. There is a possibility we are able to sequence dino-DNA because gut muscles seem well preserved. Photos are shown below.
