The oldest known "footprints" left by an animal have been uncovered in southern China.
中國南部發現了世上最古老的一種動物“腳印”。
The identity of the creature that made the 546-million-year-old tracks is still unknown, but they come from the period when the earliest animals are thought to have evolved.
該5.46億年前的足跡來自何種生物仍然未知，但是其來自被認為來自最早的動物進化的時期。
The fossil consists of two rows of imprints that represent the earliest known record of an animal with legs.
化石由兩排印記組成，代表了關於最早已知的有腿動物的記錄。
The research by a Chinese team appears in Science Advances journal.
該中國團隊的研究刊登在《科學進展》雜誌上。
Team-members are unclear whether the creature had two legs or several. But they say the tracks probably belong to a bilaterian.
團隊成員不清楚該生物是否有兩條腿或多條腿。但他們說這些腳印可能屬於一個兩側對稱動物。
This is a group of animals characterised by having paired appendages - in this case, perhaps, paired legs. They are one of the most diverse animal groups in existence today.
這組動物的特徵是具有成對的附肢 - 在這個案例中，可能是成對的腿。它們是現今最多樣化的動物群體之一。
These legs raised the animal’s body above the sediment it was moving across.
這些腿把該動物的身體提高，讓其能夠在沉積物上方移動。
The trackways were found in the Yangtze Gorges area of South China. The rocks they come from are dated to between 551 million and 541 million years old.
腳印是在華南長江三峽地區發現的。它們所在的的岩石年齡在5.51億到5.41億年前之間。
"Previously identified footprints are between 540 and 530 million years old. The new fossils are probably up to 10 million years older," the study’s co-author Zhe Chen, from the Chinese Academy of Sciences, told AFP.
該研究的合作者，來自中國科學院的陳哲告訴法新社：“以前發現的足跡在5.4億至5.3億年之間，新的化石可能長達1000萬年。”
He added: "At least three living groups of animals have paired appendages (represented by arthropods, such as bumblebees; annelids, such as bristle worms; and tetrapods, such as humans).
他說：“至少有三個動物群體擁有配對的附肢（包括節肢動物，如大黃蜂;環節動物如鬃蟲;以及四足類，如人類）。
"Arthropods and annelids, or their ancestors, are possibilities."
“（該物種為）節肢動物和環節動物，或是的祖先，都有可能。”
The animal appears to have paused from time to time, since the trackways seem to be connected to burrows that may have been dug into the sediment, perhaps to obtain food.
這只動物似乎不時停下來，因為這些腳印似乎與沉積物下被挖掘的洞穴相連，也許是為了獲得食物。
