publication of the Geological Survey by Dr. T. W. Stanton on "The Fauna of the Cannonball Marine Member of the Lance Formation." Following the review Profesor Schuchert announces his opinion that the evidence binds invertebrate paleontologists and geologists together in the conviction that the Lance and the Fort Union are of Mesozoic time. The U. S. Geological Survey should now reverse its former conclusion and adapt itself to the fuller evidence.

In the first conclusion Professor Schuchert adopts the view of Dr. Stanton and of Messrs. Lloyd and Hares, who described and named the Cannonball beds in 1915, as to the Lance formation, but goes even further than they do in assigning the Fort Union to the Mesozoic. However, it does seem difficult to justify a separation of these formations, making one Cretaceous and the other Eocene. As a geologist long interested in the Cretaceous-Eocene problem of the Rocky Mountain region, I wish to comment that Professor Schuchert is not warranted in assuming to speak for geologists inasmuch as he does not regard much of the geological evidence. Nor does he give due weight to paleontological data, aside from those of the mollusca. Moreover, it seems gratuitous to assume that the Geological Survey, because it has not adopted the conclusion reached by Professor Schuchert, has not considered in its decisions the bearing of facts concerning the Lance secured by its own investigators some years ago. The Survey geologists have also secured much other evidence.

Now it is perfectly well known to Professor Schuchert that the question as to the age of the Lance and Fort Union beds is a part of a very large problem, involving a conception of the geologic evolution of the whole Rocky Mountain Province from Mexico to far north in Canada. More than a score of more or less local formations, younger than the great continuous Cretaceous section and older than the Wasatch Eocene, are to be correlated and interpreted. These formations present a great Ideal of varied evidence as to the history of the Cretaceous-Eocene transition period. The Survey has, in fact, based its action, with

clearly Eocene by Knowlton. This view was not seriously opposed until the flora, first found in the Fort Union, was traced down through the Lance almost to its base. The flora thereby lost much of its interest to vertebrate and invertebrate paleontologists, but not to paleobotanists or geologists.

The Fort Union beds have a mammalian fauna of small forms considered to prove the Eocene age of the strata containing them until allied types were found in the Lance associated with dinosaurs and other supposed Cretaceous forms. The significance of the poor little mammals has seemed to disappear, from certain standpoints, but not from all. The Ceratops fauna of the Lance is closely similar to that of the Denver beds, correlated by the Geological Survey, together with other Colorado and New Mexico formations, with the early Eocene beds of the Gulf region.

The Cannonball shales demonstrate the temporary return of marine waters from an unknown and as yet undiscussed region to the Dakota district, after an absence which was of considerable duration. Where was this sea meanwhile? The known Cannonball fauna consists of two sharks, several corals and foraminifera, all of which range into the Tertiary, and 60 molluscan species. The molluscan group, according to Stanton, has the general aspect of a Tertiary fauna," but he considers 24 species to be identical with forms in the Fox Hills or Pierre formations of the Cretaceous nearby, while not one is identical with any known form in the lowest Eocene of the Gulf region and 35 are new species.

Dr. Stanton has given, in the excellent publication reviewed by Professor Schuchert, a careful description of the Cannonball fauna and discussed its relationships to Cretaceous and Gulf Eocene faunas. Elsewhere he has discussed the age of the Lance on general grounds but he has always given the greatest weight to the character of the invertebrate fauna, as is natural considering his special point of view.

invertebrate paleontologist to give some attention to the possibility that a northern isolated sea existed into early Eocene time and that its conditions produced a modification of the Cretaceous molluscan fauna naturally different from that arising during the same time in the Gulf region. Does not the Cannonball fauna show what modification had been reached at a time which, under the existing conditions, must be placed in the general time scale by utilizing, instead of ignoring, the other facts of the Lance and Fort Union formations, and also the concordant knowledge of Rocky Mountain history?

TO THE EDITOR OF SCIENCE: In SCIENCE for January 14, 1921, Professor Schuchert, in reviewing Dr. Stanton's recent paper on The fauna of the Cannonball marine member of the Lance formation," proceeds to answer this query in a most emphatic and unreserved affirmative. He assumes to speak with authority for geologists and vertebrate and invertebrate paleontologists, but he admits that the "floral brethren" will, of course, continue to dissent. The problem of establishing the line between Cretaceous and Tertiary time in the Rocky Mountain province has been more or less of a storm center for a number of years, but the question can only be settled when all the available lines of evidence have been evaluated and harmonized. Drawing this line at the top of the Fort Union will profoundly affect other areas and other problems, many of which Professor Schuchert appears to have underestimated if not indeed overlooked.

The faith that is in the "floral brethren " is strong! This evidence has been set forth at length on several occasions, but a brief recapitulation may not be without interest. Up to the present time, with one or two minor exceptions, the Fort Union has been everywhere accepted as of Eocene age. It has a very large flora of approximately 500 species. Aside from local stratigraphic and paleontologic considerations, the Eocene age of the

Fort Union flora is attested by its affil with many European Eocene deposi definite, acknowledged position, as Ard Mull, Gelinden in Belgium, and Sezar the Paris Basin, as well as the I in Greenland and Alaska. This affil amounts to many identical and closely species, as well as identical and related g Several Fort Union species are believed still living, a condition not known fo earlier American deposit.

The flora of the Lance formation is rich one, comprising about 125 forms, of which, however, are so fragmentar obscure as to be incapable of more generic determination. After eliminati new forms and those that can not be sp ally named there are 87 species that are tively identified, all but 15 of which 80 per cent.) are found in the Fort I It is unmistakably a Fort Union flora occurs through the whole vertical range Lance formation, some of the most cha istic Fort Union plants being found four feet of the base of the beds. ( entire known Lance-Fort Union flora les 15 species have been reported from Cret beds anywhere, and this number will duced instead of enlarged by revision floras involved.

Sedimentation was undoubtedly cont through the Lance and Fort Union tions; in fact, it is impossible to dra satisfactory line between them. The 1 point at which dinosaurs occur is tal the top of the Lance, but where these r are absent it has no recognized or recog top. If the Cannonball marine member Lance formation is Cretaceous ther Lance and Fort Union are Cretaceo there is no stopping point short of the the Fort Union. Professor Schucher holds that there "is here a continuo unbroken series of deposits from the and Fox Hills into the top of the Fort and that the reported erosion contacts b the several formations are due to I more than changes from marine to b and fresh-water deposition, or to irregu
