Japanese schoolgirl finds 130 million-year-old fossil

YUASA, Wakayama — An elementary school girl found fossils of a previously unknown species of shrimp here in a layer of the earth’s crust some 130 million years old, the Wakayama Prefectural Museum of Natural History has announced.

Natsumi Kumagai, a fourth-year elementary school student in Hannan, Osaka Prefecture, made the find when she took part in a fossil hunt hosted by the museum in Yuasa in December last year. Kumagai initially took the fossils home, but after museum curators reexamined them, the find turned out to be a previously unknown species of shrimp.

The new shrimp, which belongs to the genus of the extinct Hoploparia of the Nephropidae family, has been named after Kumagai — “Hoploparia natsumiae.” The “ae” added after “Natsumi” indicates feminine gender in Latin.

“I’m surprised to know that the fossils I found were that of a new species,” says Kumagai. “I’m happy that my name will live on forever.”

The museum says that fossils of 16 species in the same genus from 130 million years ago have been discovered around the world. The “Hoploparia natsumiae” fossils are the second species found in Japan, following another discovered in Gunma Prefecture.

Besides the “Hoploparia natsumiae,” fossils of six different and previously undiscovered species were found in the same stratum. The fossils will be displayed at the museum from Saturday.

新種エビ化石:菜津美ちゃんが発見 学名「ナツミアエ」

 和歌山県湯浅町栖原(すはら)の白亜紀前期(約1億3000万年前)の地層で、大阪府阪南市の市立尾崎小4年、熊谷菜津美さん(9)が、新種のエビの化石を発見した。10日発表した同県立自然博物館によると、絶滅したアカザエビ科ホプロパリア属の一種で、熊谷さんの名前にちなみ、学名は「ホプロパリア・ナツミアエ」。「アエ」はラテン語で女性であることを示すという。熊谷さんは「新しい発見と聞いてびっくりした。自分の名前がずっと残るからうれしい」と顔をほころばせた。

 熊谷さんは同館友の会会員で、昨年12月に化石を探すイベントに初参加。化石は一度持ち帰ったが、同館学芸員らが改めて調べ、新種と判明した。頭胸甲(とうきょうこう)(長さ30ミリ)、腹部(同23ミリ)、ハサミ部分の鋏脚(きょうきゃく)(同51ミリ)に分かれていた。

 同館によると、これまでに発見された白亜紀前期の同属の化石は世界で16種で、国内では群馬県に次いで2例目。甲殻類化石に詳しい岐阜県瑞浪市化石博物館の柄沢宏明学芸員(古生物学)は「ホプロパリア属の進化や分布を考える上で大変貴重」と話した。

 同じ地層から、他にも新種の甲殻類化石6種が見つかっており、計7種を13日から和歌山県立自然博物館で展示する。【清水有香】

2008-08 Mantide in ambra dal Cretaceo del Giappone

87 Million Year-Old Praying Mantis Found

080425-amber-mantis_1701 87 Million Year-Old Praying Mantis Found pictureIs the 87-million-year-old praying mantis recently found encased in amber in Japan a “missing link” between mantises from the Cretaceous period and modern-day insects?

It is a rare find indeed and its true significance is still to be deciphered.

Discovered in January of this year by Kazuhisa Sasaki, director of the Kuji Amber Museum, the fossil mantis measures 0.5 inch (1.4 centimeters) from its antennae to the tip of its abdomen.

It was found buried more than six feet below the surface of an amber mine in a part of Japan that is famous for producing large amounts of amber, the northeastern Iwate Prefecture.

“I found it in a deposit that had lots of other insects—ancient flies, bees, and cockroaches—but this was the only praying mantis” said Sasaki.

The fossil mantis is partially well preserved, although its wings and abdomen are badly crushed.

According to Kyoichiro Ueda, executive curator of the Kitakyushu Museum of Natural History, it is the oldest mantis fossil ever found in Japan and only one of seven in the entire world from the Cretaceous Period.

Even more unique is the fact that this mantis is different from the other six, in that it has two spines protruding from its femur and it has mysterious, tiny hairs on its forelegs.

No mantis from this particular time period has ever been found with spines, although modern mantises have five or six on their forelegs, which help them catch prey.

“The years of the late Cretaceous period were a kind of transition phase between the ancient and modern worlds, and this fossil displays many intermediate elements between the two eras” said Ueda.

Time alone will reveal the significance of this important find.
