歡迎來到BugsDirect Ltd. 全球昆蟲標本領先供應商（零售/批發）
來自全球最著名古生物學地層之一的真正始新世化石魚類。
Knightia alta 約在 3,390 萬至 5,600 萬年前，棲息於始新世北美廣袤的淡水湖泊中。牠們在分類學上與鯡魚及沙丁魚近親，成群活動，以藻類、矽藻、昆蟲，偶爾也捕食較小型魚類為食。其特徵包括厚重的鱗片、細小的圓錐形牙齒，以及從頭部後方延伸至中線鰭部、排列獨特的背側與腹側骨板。在地球上最豐富的脊椎動物化石之列，Knightia 仍因其出色的保存狀態，以及為任何自然史收藏帶來的鮮明視覺效果而備受珍視。
美國懷俄明州的格林河組以其魚類化石的卓越品質聞名全球。這些化石保存於細粒油頁岩中，能以非凡的細節呈現骨骼形態。
請注意：這些是真正的化石。整理人員通常會在基質上施加棕色保護性染料，並輕微重建鰭的位置，以便呈現標本的形態與背景。每件標本均從符合所述尺寸範圍的現貨中挑選——如同所有天然標本，其色彩、基質特徵及保存狀況均會有所不同。所示圖片僅供參考。

展示與收藏：
適合各級收藏家的醒目且易於入手的化石。無論作為壁掛式基質標本，或陳列於史前魚類或格林河組專題櫃中，都十分美觀。也很適合與同一地層的其他始新世標本搭配收藏，包括 Plecia pealei 化石蠅及植物化石。
