Iwate Prefectural museum geological feature observation society held "we read stratum of the Cretaceous of Sanriku Geopark"

We observed stratum approximately 100 million years ago from now called "the Cretaceous" to hang in Kuji-shi from Nodamura in this Iwate that became the 73rd on Sunday, July 2, 2017 Prefectural museum geological feature observation society, and to open. It became ideal day for perfect observation party blessed with weather.

Because many fossils are found, we can find not only creature of the sea and the land but also fossil "amber" of sap for celebrity from this stratum.

In addition, we were able to see not only creature itself but also sign (called Lebensspur fossil) of den of creature. It was place that we easily passed by, but when there were today's lecturer, commentary of Mochizuki curator, eyes were spread out in the details, and eyes of participant considerably got fat, and there was normally much discovery.

We can see made stratum recently at this place. It is sediment caused by 2011 off the Pacific coast of Tohoku Earthquake tsunami. Furthermore, there was stratum to sail up until approximately 7,000 years before it was in Jomon period when the details were clarified by Mr. Onodera (Morioka City high school), and, in the bottom, stratum thought to be sediment of tsunami of 18 levels was confirmed in that. We show that tsunami is repeated many times in this ground.

We moved to Kuji Amber Museum and experienced amber excavation in the afternoon. Participant dreamed of tortoise and crocodile, fossil discovery of dinosaur including amber to one hand with ice pick and dug the earth which dinosaur walked silently. Unfortunately there was not discovery of fossil, but amber varied in size from small to large, but seemed to be able to find most of participants.

In fact, to cliff and rock to see in the same way everywhere, it was at valuable opportunity to notice that various stories hid. As more stories are engraved into the earth of Sanriku, please come again by all means.
