Radiocarbon age constraints for late Pleistocene–early Holocene artifacts and portable art work from Jalisco, Mexico, carved from bones of the last elephants of North America

晚更新世和早全新世艺术的记录在新大陆是非常罕见的，与来自欧洲和中东的丰富档案相比，这些档案可以追溯到3万年前(BP)，甚至更多。在这里，我们展示了来自墨西哥中西部哈利斯科州的迄今为止未知的异常精心制作的便携式艺术品和工具，它们是已知的美洲最古老的作品之一。这些文物是由鼻目动物的长骨和象牙碎片以及其他被认为是典型的更新世的大型动物元素雕刻而成的。然而，根据这些化石的生物磷灰石的初步14C年龄表明，用于艺术性骨改造的动物可能在更新世末期大灭绝后幸存下来，并与人类共存约7.6ka。BP。我们在这里申请资助，对2019年3月在瓜达拉哈拉古托洛吉科博物馆采集的更多考古和古生物材料进行14C辐射年龄测定，以支持我们的假设。

The record of Late Pleistocene and Early Holocene art is remarkably rare in the New World as compared to rich archives dating back to 30,000 years before present (BP), and more, from Europe and the Middle East. Here we present hitherto unknown pieces of unusually elaborate portable art work and tools from Jalisco state in west-central Mexico, which are among the oldest known from the Americas. These artifacts are carved from long bone and tusk fragments of proboscideans and other megafaunal elements considered as typically Pleistocene in age. Nevertheless, initial 14C ages based on bioapatite of these fossils suggest that the animals used for artistic bone modification may have survived the end-Pleistocene- mass extinction and coexisted with humans to about 7,6 ka cal. BP. Here we apply for funding of 14C radiometric age dating of additional archaeological and palaeontological material sampled at the Museo Paleontológico de Guadalajara in March 2019, to support our hypothesis.
