How many more such cases there may have been in these "three bone-beds full" of similar remains, it would be interesting to know. But though somewhat aside from the present subject, I cannot refrain in passing from referring to the wonderful preservation of these remains. It is preposterous to say that these bones have lain thus exposed to the weather for the millions of years postulated by the popular theory. There is not a particle of scientific evidence to prove that they are not just as recent as any specimen from the Tertiaries or the Pleistocene. Buffon and Cuvier proved the mammals to be of "recent" age, because they occurred in the superficial deposits. They never heard of the Triassic, Jurassic, and Cretaceous of Colorado and Wyoming, nor these Permian of Texas. Think of this frog's teeth "like the points of cambric needles," and he and his fellows "as perfect as if they had died a month ago." Of one of the big six-foot specimens this author says: "Its head was so beautifully preserved, and cleaned under long erosion, it was difficult to believe it was not a recent specimen." While of the little six-inch fellow referred to above he says: "The bones of the skull are perfectly preserved, quite smooth, and show the sutures distinctly; there is no distortion, some red matrix attached below seems absolutely necessary to convince the mind that it is not =a thing of yesterday=." James Geikie[62] mentions the case of the Elgin sandstones "formerly classed as 'Old Red,'" but which are now called Triassic, "from the fact that they have yielded reptilian remains of a higher grade than one would expect to meet with in old Red Sandstone." Since these strata =slide up and down so easily=, we have here far more urgent scientific reasons for calling these amphibian remains of Texas among the most "recent" geological deposits on the globe. But I must return to my subject. The Invertebrates are also eloquent to the fact of abnormal conditions having prevailed when their remains were entombed. We could go through the whole list, but it is the same old story of abnormal deposits, essentially different from anything that is being made to-day.
