格雷化石遗址的第一具短脸熊颅骨化石
Gray Fossil Site with the short-faced bear skull fossil
2011年12月17日
格雷化石遗址（Gray Fossil Site）化石挖掘工作已经开展了8年多时间了，最近科学家们也是首次在这里发现了短脸熊（short-faced bear，Plionarctos）化石。这类短脸熊最早由东田纳西州立大学（East Tennessee State University）的研究人员2003年所发现，当时也仅发现了一个下颌骨和几颗牙齿化石。
Gray Fossil Site (Gray Fossil Site) fossil excavation work has been carried out for more than eight years, recently scientists are also here for the first time found the fossil of a short-faced bear (short-faced bear, Plionarctos). Such short-faced bears the earliest researchers from East Tennessee State University (East Tennessee State University) discovered in the year 2003, was only found a mandible and a few teeth fossils.
而就在过去几个月时间里，这类短脸熊化石终于有了新的发现，一块带牙齿不完整的颅骨化石，以及另外一头短脸熊的上颌骨和牙齿。
Just in the past few months, such short-faced bear fossils finally a new discovery, one with teeth incomplete skull fossil, and a short-faced bear maxilla and teeth.
古生物学家Blaine Schubert博士说道：“这是一个重大的发现，因为Plionarctos化石是一类非常非常稀少的短脸熊化石，已发现的只有部分下颌骨和下排牙齿，此次发现将有助于我们进一步了解这类短脸熊到底长什么样子，平常吃什么，以及与其它熊类的亲缘关系。”
Paleontologist Dr. Blaine Schubert said: "This is a significant finding, because Plionarctos fossil is a class of very, very rare short-faced bear fossils have been found in only a portion of the mandible and lower teeth, the discovery will help learn more about this type of short-faced bear look like in the end, what to eat, as well as with other bears kinship. "
Schubert补充道：“Plionarctos是属于美洲另一种著名古短脸熊tremarctines的一个分支，是包括冰河时期巨型短脸熊，现生南美眼镜熊在内的所有后期古短脸熊tremarctines的其中一类祖先。因此此次所发现的Plionarctos短脸熊化石对于深入研究这类神奇动物的演化历史来说是非常重要的化石材料。”
Schubert added: "Plionarctos is belonging to the Inter-American another famous ancient short-faced bear tremarctines, a branch, including Ice Age giant short-faced bear, modern spectacled bear of South America, including all the late ancient short-faced bear tremarctines one therefore found the ancestors. Plionarctos short-faced bear fossils-depth study of the evolutionary history of the kind of magical animals is very important fossil material. "
格雷化石遗址2000年最早发现，在远古时期，这里曾是一个大型动物“坟场”，大量史前动物落入其中。这里还是世界上在单一化石产地发现貘（tapir）化石最多的地方，除此以外，这里发现的化石还有马、海狸、犀牛、鳄鱼、蜥蜴和蛇化石，另外还发现了两种新物种：Arctomeles dimolodontus（一种獾），Pristinailurus bristoli（一种小猫熊）。
Gray Fossil Site in 2000 first discovered in ancient times, there was a large animal, "Cemetery", in which a large number of prehistoric animals fall into. Here is the world discovered a single fossil origin the tapir (tapir) Fossil place, In addition, the fossils found here as well as horse, beaver, rhinoceros, crocodiles, lizards and snakes fossil also discovered two new species: Arctomeles dimolodontus (a badger), Pristinailurus bristoli (a kitten Bear).
此次Plionarctos短脸熊化石发现的另一个重要意义是首次确定了格雷化石遗址的年龄，大约是在距今450到700万年左右。
Another significance of the Plionarctos short-faced bear fossils found for the first time to determine the age of the Gray Fossil Site, about dating back 450-700 million years or so.
(Note: That can't be right. Perhaps 4.50 – 7.00 million years ago.)
