PERMIAN VERTEBRATE FOSSILS IN TEXAS 743 



megacephalus, Cricotus crassidiscus, Diadectes phaseolinus, D. 

 latihuccatus, Empedias molaris, Pariotichus brachyops, Pantylus 

 cordatus, Clepsydrops natalis, C. limhatus, Dimetrodon semiradicatus, 

 Metamosaurus josssatus, Paleosaurus uniformis, Embolohusf ritillus 



So far as known none of these species occur above the Wichita 

 beds. 



As has been stated, the continuations of these beds to the south 

 comprise deposits of deeper water and carry a large invertebrate 

 fauna. The details of the stratigraphy and fossils of this division 

 on the Colorado river are given by Dr. Drake in the Fourth Ann. 

 Rep. Geol. Sur. Tex., pp. 421 ff. 



Ballinger and North of Abilene, the localities of Professor Hyatt's 

 cephalopods, are well known. They are the same horizon as that 

 of Military Crossing. 



LOCALITIES OF CLEAR FORK DIVISION 



Coffee Creek. — In the northeastern corner of Baylor County, about 

 four miles west of Military Crossing, a small stream, generally dry, 

 runs into the Big Wichita River from the north. The old cattle 

 trail crossed the Big Wichita River about three miles above the mouth 

 of Coffee Creek. As will be seen, this was a very prolific locality 

 for collectors: 



Fossils: Diplocaulus magnicornis, D. limhatus, D. sp., Trimer- 

 orhachis mesops, Zatrachys micropthalmus, Eryops sp., Acheloma 

 cumminsi, Anisodexis imbrocarius, Diadectes phaseolinus, D. sp., 

 Pariotichus aguti, Capiorhinus angusticeps, Pantylus tryptychus, P. 

 coicodus, Labradosaurus hamatus, L. sp., Dimetrodon gigas, D. dol- 

 lovianus, N aosaurus claviger , N. cruciger,N. macrodus, Edaphosaurus 

 pagonias 



Boneyard. — The old cattle trail from the south to the north, at the 

 time the Cope collections were made, crossed the Big Wichita River 

 about two and a half miles above Coffee Creek. Just east of that road, 

 on the north side of the river, is an area of "bad lands." At this 

 place there were a great number of fragments of vertebrates, so much 

 so that Mr. Sternberg gave it the name of "Boneyard" and so labelled 

 many of the fossils collected by him. 



Fossils: Diadectes sp., Empedias sp.
