踩在三叶虫上的足印1938年美国肯塔基州柏里学院地质系主任柏洛兹博士宣布,他在石炭纪砂岩中发现10个类人动物的脚印。显微照片和红外线照片证明,这些脚印是人足压力自然造成,而非人工雕刻。据估计,有人足痕迹的这些岩石距今约有2.5亿年。更早一些时候,有人在美国圣路易市密西西比河西岸一块岩石上,曾发现过一对人类脚印。据地质学家判断,这块岩石距今约有2.7亿年。最为奇特的发现,是在美国犹他州羚羊泉。业余化石爱好者米斯特于1968年6月发现了几块三叶虫化石。他叙述说,当他用地质锤轻轻敲开一块石片时,石片“像书本一样打开,我吃惊地发现,一片上面有一个人的脚印,中央处踩着三叶虫,另
Footprints on Trilobites 1933 Dr Boltzz, director of the Department of Geology at Barry College in Kentucky, USA, announced that he had found 10 humanoid footprints in Carboniferous sandstones. Photomicrographs and infrared photographs show that these footprints are caused by the pressure of human footprints, not artificially engraved. It is estimated that there are some 250 million years ago of these rocks with traces of human existence. Earlier, someone had discovered a pair of human footprints on a rock on the western bank of the Mississippi in the city of St. Louis. According to the geologists to judge, this rock dating back about 270 million years ago. The most peculiar discovery is in the Antelope Springs, Utah, USA. Amateur fossil enthusiast Myrist discovered several trilobite fossils in June 1968. He recounted that when he tapped a piece of stone gently with a geo-hammer, the piece of stone "opened like a book, and I was surprised to find that there was a man’s footprints above it, a trilobite at the center, and another
