Scientists found a bone from 1985. It is the first dinosaur bone from Antarctica.

科學家發現了一塊 1985 年的骨頭，這是南極洲發現的第一塊恐龍骨。

Dr. Mike Thomson found the bone on an island. It is a small piece of a back bone. For 40 years, it was in a museum. Then, Dr. Mark Evans looked at it. He found it is from a titanosaur. This dinosaur had a long neck and ate plants.

Mike Thomson 博士在一個島上發現了這塊骨頭。它是一塊很小的脊椎骨。它在博物館存放了 40 年，接著 Mark Evans 博士對其進行研究，發現它來自於一隻泰坦龍。這種恐龍擁有長頸且以植物為食。

This dinosaur lived 82 million years ago. Adult titanosaurs were very big. But this dinosaur was small. It was maybe 6 or 7 meters long. The bone was in the sea rock. The dinosaur probably died and floated into the ocean.

這種恐龍生活在 8,200 萬年前。成年的泰坦龍體型非常巨大，但這隻恐龍較小，長度可能只有 6 或 7 公尺。這塊骨頭位於海岩之中，恐龍可能是死亡後漂流到了海洋中。

This find helps scientists. It shows that dinosaurs walked from South America to Australia. They used Antarctica as a bridge. Now, the ice is melting. Scientists think they will find more dinosaurs soon.

這次發現對科學家很有幫助。它顯示恐龍從南美洲走向澳洲，將南極洲作為一座橋樑。現在冰層正在融化，科學家認為很快會發現更多恐龍。

This bone proves dinosaurs lived in Antarctica. It shows how they moved to other lands.

這塊骨頭證明了恐龍曾生活在南極洲，並顯示了它們如何移居到其他土地。

A fossilized bone, collected in 1985, has been officially identified as the first dinosaur remain ever found on the Antarctic continent.

一塊於1985年採集的化石骨骼，現已正式被鑑定為南極洲發現的第一件恐龍遺骸。

The specimen was found by geologist Dr. Mike Thomson on James Ross Island during a British Antarctic Survey (BAS) expedition. At first, the 10-centimeter bone was simply described as belonging to a large reptile. However, after nearly forty years in storage, paleontologist Dr. Mark Evans re-examined the bone. Through comparative analysis, he confirmed that the vertebra belonged to a titanosaur, which was a type of long-necked, plant-eating dinosaur.

該樣本是由地質學家 Mike Thomson 博士在英國南極調查局 (BAS) 的考察期間，於詹姆斯羅斯島發現的。起初，這塊10公分長的骨頭僅被描述為屬於一種大型爬行動物。然而，在存放近四十年後，古生物學家 Mark Evans 博士重新檢查了該骨骼。透過對比分析，他確認該椎骨屬於泰坦龍，這是一種長頸的植食性恐龍。

This specific dinosaur lived during the Late Cretaceous period, about 82 million years ago. While adult titanosaurs could weigh 15 tons and reach 37 meters in length, this individual was likely a juvenile or a small adult, measuring only six to seven meters. Because the fossil was found in marine rock, researchers believe the body likely floated from the coast to the seabed after the animal died.

這種特定的恐龍生活在約 8,200 萬年前的白堊紀晚期。雖然成年泰坦龍的體重可達 15 噸，長度可達 37 公尺，但該個體可能僅為青少年或小型成年個體，長度僅 6 到 7 公尺。由於該化石發現於海洋岩石中，研究人員認為該生物在死亡後，屍體可能從海岸漂浮至海床。

From a scientific perspective, this discovery helps experts understand how dinosaurs moved across the ancient supercontinent of Gondwana. Researchers emphasize that the presence of titanosaurs in Antarctica suggests there was a land bridge allowing dinosaurs to travel between South America and Australia. Furthermore, this find shows that museum archives are still very useful for discovering new data. Experts suggest that more fossils may be found in the future as melting glaciers, caused by climate change, reveal previously hidden layers of rock.

從科學角度來看，這一發現有助於專家了解恐龍如何在古代超級大陸岡瓦那之間移動。研究人員強調，南極洲出現泰坦龍表明當時存在一座陸橋，允許恐龍在南美洲與澳洲之間往來。此外，這次發現顯示博物館的檔案對於挖掘新數據依然非常有價值。專家建議，隨著氣候變遷導致冰川融化，先前隱藏的岩層將被揭露，未來可能會發現更多化石。

The reclassification of this 1985 specimen confirms the earliest known presence of dinosaurs in Antarctica and provides important information about how animals migrated during the Cretaceous period.

對這個1985年樣本的重新分類，確認了恐龍在南極洲出現的最早紀錄，並為白堊紀期間動物如何遷徙提供了重要資訊。

A fossilized vertebra, collected in 1985, has been formally identified as the first dinosaur remain discovered on the Antarctic continent.

一件於 1985 年收集的骨化脊椎骨，已正式被確認為在南極大陸發現的第一件恐龍遺骸。

The specimen was recovered by geologist Dr. Mike Thomson on James Ross Island during a British Antarctic Survey (BAS) expedition. Initial field documentation categorized the 10-centimeter diameter bone as belonging to a large reptile. Following nearly four decades of storage within the BAS geological collections, the specimen was re-evaluated by paleontologist Dr. Mark Evans. Subsequent comparative analysis confirmed the vertebra as belonging to a titanosaur, a genus of long-necked sauropod herbivores.

該標本是由地質學家 Mike Thomson 博士在英國南極調查局 (BAS) 的考察期間，於詹姆斯羅斯島發現的。最初的現場記錄將這塊直徑 10 公分的骨骼歸類為大型爬行動物。在 BAS 地質收藏品中存放近四十年後，古生物學家 Mark Evans 博士對該標本重新進行了評估。隨後的對比分析確認該脊椎骨屬於泰坦巨龍 (titanosaur)，這是一種長頸龍類草食動物。

Chronologically, the specimen dates to the Late Cretaceous period, approximately 82 million years ago. While adult titanosaurs are characterized by masses reaching 15 metric tons and lengths of 37 meters, this specific individual is estimated to have been a juvenile or small adult, measuring approximately six to seven meters. The geological context suggests the specimen was deposited in marine rock, likely following a post-mortem drift from the coastline to the seabed.

在年代上，該標本可追溯至白堊紀晚期，約 8,200 萬年前。雖然成年泰坦巨龍的特徵是重量可達 15 公噸且長度 37 公尺，但該特定個體估計為幼年或小型成年個體，長度約六至七公尺。地質背景顯示，該標本沉積於海洋岩石中，很可能是死後從海岸線漂流至海床。

From a biogeographical perspective, this finding facilitates a deeper understanding of dinosaur dispersal across the southern supercontinent of Gondwana. Researchers posit that the presence of titanosaurs in Antarctica suggests a terrestrial corridor facilitating movement between South America and Australia. Furthermore, the discovery underscores the utility of curated museum archives in yielding new scientific data. It is hypothesized that further biodiversity evidence may emerge as glacial retreat, precipitated by climatic shifts, exposes previously inaccessible strata.

從生物地理學角度來看，這一發現有助於深入了解恐龍在南半球超級大陸岡瓦那 (Gondwana) 的分佈情況。研究人員認為，南極洲存在泰坦巨龍表明當時存在一個陸地走廊，方便其在南美洲與澳洲之間移動。此外，此發現突顯了博物館館藏在產出新科學數據方面的價值。研究人員假設，隨著氣候變化導致冰川退縮，暴露出先前無法接觸的地層，未來可能會出現更多生物多樣性的證據。

The reclassification of this 1985 specimen confirms the earliest recorded presence of dinosaurs in Antarctica and provides critical data on Cretaceous faunal migration.

將 1985 年的標本重新分類，確認了南極最早記錄到恐龍出現的證據，並為白堊紀動物遷徙提供了關鍵數據。
