FOSSIL VERTEBRATES FROM FLORIDA 

 BY E. H, SELLARDS 



{Abstract) 



This paper, illustrated by maps and diagrams, brought out additional facts 

 of great interest on a subject discussed by Doctor Sellards in the July number 

 of the American Journal of Science, concerning human bones and artifacts 

 found in association with a number of extinct animals. The mineralized char- 

 acter of the bones, their scattered condition — in these respects resembling the 

 other fossil animals — the undisturbed stratum, and the unbroken continuity of 

 the overlying rock, all indicate the undoubted presence of man in this country 

 during the Pleistocene period. 



Dr. O. P. Hay vouched for the authenticity of this discovery, even though 

 anthropologists are wont to question the association of the human remains 

 with the true Pleistocene forms. He considered the fauna as of early Pleisto- 

 cene age and cited evidence for this view. Doctor Matthew observed that he 

 regarded the opinions of expert collectors of fossil vertebrates as to the validity 

 of this discovery as carrying great weight, more probably, than the strati- 

 graphic data. 



CAMPODUS AND EDESTUS REMAINS 

 BY C. R. EASTMAN 



{Alfstract) 



The very peculiar dentition of a shark was exhibited, which, being coiled, 

 resembled more the form of an ammonite, and would hardly be taken for a 

 vertebrate specimen by the casual observer. The teeth of the modern shark 

 also come in succession, but this primitive animal had a great battery or coil 

 situated anteriorly in its mouth, which furnished a constant supply of dental 

 armature. 



BRONTOTHERIUM: A NEW MOUNT IN THE YALE MUSEUM 

 BY R. S. LULL 



{Abstract) 



This specimen, shown by lantern slides, recently mounted in the posture of 

 the famous model by Charles R. Knight, is the holotype of Brontops rohustus 

 Marsh {Brontothcrium rohustum Marsh). It is a specimen in excellent preser- 

 vation and one unusually complete, which lay in the Yale Museum, spread out 

 on the shelves, since 1875. It is one of the largest and finest of the Titano- 

 theres, but not the most extremely specialized. 



BAROSAURUS: A GIGANTIC SAUROPOD DINOSAUR 

 BY R. S. LULL 



(Abstract) 



Barosaurus is one of the gigantic dinosaurs of which a large portion of the 

 backbone is known. It resembles Diplodocus, which it rivals in size. The
