ノジュール外形を修復復元してます。化石表面への着色・補修はしておりません。

大分県玖珠郡野上層産出。 サクラマス(ビワマス)またはヤマメ(アマゴ)のノジュール化石。
約50万年前。化石本体約25㎝。ノジュール重量1102g。1988年採集。

当地の魚ノジュールは珪藻土が硬化したものです。通常はノジュール外周まで結構硬いのですが、まれに一番外側の層の硬化度が不十分なものがあります。この標本も外周が約1㎝と厚く、硬化度が不十分なノジュールでした。発掘時とクリーニング作業の過程で8枚目の画のように、外周の一部を破損しましたので、エポキシ樹脂で地層中でのノジュール形態を修復復元しております。

また、通常はノジュールを水につけ冷凍したのち、焼いて急冷。赤道面にヒビを入れて、2つに割るのですが、当標本は外周が厚く、熱が十分に中まで伝わらず、顔の部分しか露出できませんでした。そのため約半年かけて全身を削りだしてます。

化石表面保護のために透明ワックスを塗布してます。着色はしておりません。

化石本体は約25㎝のミドルサイズ。当地のヤマメ化石は15㎝前後が普通。ちょっと大きいですが、サクラマス(ビワマス)ではなく、成長したヤマメ(サクラマスの陸封型)だと思います。顔が分解していたり、尾部までジュール化しないものや胴体中央部でノジュールが途切れているものが多く、このように尾びれまで全体がノジュール化した標本で20㎝を超えるものはめったに出土しませんでした。
魚体が綺麗な姿で保存された良好な標本だと思います。

化石は乾燥剤を入れた箱に入れて、あまり直射日光を当てないでください。除湿せず、直射日光にあてて放置すると1年くらいで黒ずんでしまいます。


現地は2000年ごろまでノジュール産出層が露出しておりましたが、2025年現在産出層は埋められてしまっており、ノジュールの採集は不可能となってしまっています。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters).

1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
