Notwithstanding the amount of work done at Bigbone Lick, the geology of

the locality, and especially of the bone-bearing levels, is not well

known. Most persons who have labored there were interested almost wholly

in getting as many bones as possible and then in getting away. Cooper,

as cited, published a map of the region and indicated where the

excavations had been made up to that time. This map is here presented,

redrawn (map 41). From Cooper’s account it appears that all of the bones

had been found within a very circumscribed area, near a number of salt

springs. The bones occurred on the surface and as deep as 25 feet.

Cooper attributed this variation of depth to the unevenness of the

surface, his idea being that the bone-bearing stratum occupied a certain

level. He concluded that the valley had been filled up to a depth of not

less than 30 feet by unconsolidated beds of various kinds, of which the

uppermost was a light-yellow clay. This appeared to have been brought

down from the higher grounds by flowing water. In it were found bones of

buffaloes and other modern animals. Below this came a thinner layer of

darker color, softer and more gravelly, which contained remains of reedy

plants and fresh-water mollusks. It is described as being sometimes very

thin or even wanting. It was in this layer that the bones, or most of

them, were buried. It was itself underlain by a bed of blue clay of a

very compact and tenacious kind. Cooper added that this bone-bearing

layer appeared sometimes to be embedded in the blue clay.

The next important investigations made at this place, so far as the

writer knows, are those instituted by Professor N. S. Shaler in 1868

(Geol. Surv. Kentucky, 2d ser., vol. III, 1877, pp. 196–198; Allen’s

“The American Bison,” 1876, pp. 232–236). He reported that he had sent

to the Museum of Comparative Zoology at Harvard at least a ton of bones.

Immediately at the salt springs Shaler appears not to have been able to

discover any order in the disposition of the bones. “It is only at

points remote from the springs, where the beds seem to have been formed

by a mixture of the creek mud and the waste from the springs, that we

find the remains in the order which will enable us to form some opinion

as to the succession of occurrence of these animals at this point.” At

one place he thought he had succeeded in finding a distinct order of

succession. Just where this place was he did not indicate, nor what

kinds of deposits were passed through. The depth reached appears to have

been only 8 feet. Unfortunately, the great collection made by Shaler has

remained unstudied, except the remains of the buffalo (J. A. Allen, “The

American Bison,” 1876, with plates).

Shaler thought that the beds of glacial drift did not extend south of

Ohio River. The discovery that the Illinoian drift-sheet covers most of

Boone County (Leverett, Monogr. U. S. Geol. Surv., vol. XLI, pp.

257–258) throws much light on the history of the locality. It appears

rather strange that Shaler did not find rocks of far northern origin at

Bigbone Lick. The geologic history appears to be something like this.

When the Illinoian ice-sheet crossed the Ohio there was present the

predecessor of Bigbone Creek. Inasmuch as the glacial sheet did not

remain there long, a rather thin deposit was laid down in the creek.

This is probably represented by the bed of blue mud mentioned by Cooper.

When the glacier retired, the locality became a swamp covered probably

by vegetation and receiving mud and gravel brought there by the stream

and washed down from the surrounding hills. Doubtless the salt springs

existed then as now and attracted thither elephants, mastodons, and

other species. What were all the changes undergone there between the

Illinoian and Wisconsin drift stages can not be guessed; but during the

latter time, when the Ohio was carrying down vast quantities of

detritus, some from the glaciated regions, some from the non-glaciated,

its muddy waters were often backed up into Bigbone Creek, as they are

sometimes now, and they left there the upper yellow clay described by

Cooper, or at least most of it. When the Wisconsin stage had passed and

Bigbone Creek was free to work in that valley, erosion began. As the

creek was cutting down its bed to the present level it doubtless often

changed its position, and in this way produced the irregularity of

surface which both Cooper and Shaler mention.

Notwithstanding its widely extended reputation, Bigbone Lick has

furnished relatively few species of vertebrates, and there is question

regarding the antiquity of some of these. About the presence of _Mammut

americanum_ there is no doubt. About the presence of elephants also

there can be no question; and the writer is quite certain that both

_Elephas primigenius_ and _E. columbi_ occurred there. Undoubtedly

_Equus complicatus_ has been collected there; also _Boötherium

bombifrons_, _Symbos cavifrons_, _Bison antiquus_, and _B. bison_; but

it is not certain that the remains of the last-named species are not of

Recent times. Shaler mentions the presence of _Bison latifrons_, but he

probably had in mind _B. antiquus_. The type of _B. latifrons_ was found

in another creek valley. The occurrence of the _Cervus canadensis_,

_Odocoileus virginianus_, and _Alces americanus_ is mentioned by Cooper,

who stated that he thought he had seen traces of all of them. Shaler was

doubtful as to the elk. In Allen’s monograph on American bison, on page

234, Shaler admits the moose. The following is a list of the species

which have been reported from Bigbone Lick. References are made to pages

where further information is given on the species.

Megalonyx jeffersonii (p. 44).

Mylodon harlani (p. 44).

Equus complicatus (p. 202).

?Tapirus haysii (p. 209).

Odocoileus virginianus (p. 234).

Cervus canadensis (p. 243).

Cervalces scotti.

Alces americanus.

Bison bison (p. 270).

Mammut americanum (p. 128).

Elephas primigenius (p. 146).

Elephas columbi (p. 160).

Ursus americanus.

It is proper now to determine, if possible, during which of the

Pleistocene stages each of these species lived. It is quite probable

that none of the individual animals that have been dug up at Bigbone

Lick lived there before the Illinoian glacial stage. To find such, if

they have been preserved there, the excavations would have to be carried

much deeper. The writer assumes that any of the animals that lived there

in the interval between the Illinoian and the Wisconsin stages lived,

died, and were buried during the Sangamon stage. _Megalonyx jeffersonii_

may belong to the Sangamon or to the Late Wisconsin, for we know nothing

about the depth at which the bones and teeth were secured. _Mylodon

harlani_ is not known to have existed anywhere after the Wisconsin, and

hence we may refer it to the Sangamon. _Equus complicatus_ also may with

certainty be referred to the Sangamon; likewise _Tapirus haysii_, in

case the type was not found in South Carolina. As to the cervids

_Odocoileus virginianus_, _Cervus canadensis_, _Alces americanus_, their

status is doubtful. They might go back to the Sangamon or have lived

there at any time up to and during the Recent. The reindeer is most

likely to have existed there during the Wisconsin ice-stage. The fine

specimen of _Cervalces scotti_ at Princeton University was found in New

Jersey in deposits overlying Wisconsin drift, but it may be taken as

certain that the species had existed before the time of the Wisconsin.

There is no record of depth, matrix, or associated fossils in the case

of the type of this species, which was found at Bigbone Lick. It is

natural to refer the two species of musk-oxen to the Wisconsin stage;

but there are indications that at least _Symbos cavifrons_ has been

found at other localities in pre-Wisconsin deposits. Shaler recorded it

as being found near the bottom of his excavation with the horse and with

the bison which he called _Bison latifrons_, but which is _Bison

antiquus_. It and _Symbos cavifrons_ probably belong to the Sangamon.

From the fact that bones of the mastodon and the two species of

elephants were found by Shaler in the deeper deposits, it is probable

that the individuals represented belonged to the Sangamon or some other

pre-Wisconsin deposit; but, inasmuch as all three species lived after

the Wisconsin, there seems to be no known reason why some of their bones

may not have been buried in the late and superficial deposits at Bigbone

Lick. As to the bones of the bear found at this place little can be

said.

The numerous remains of _Bison bison_ appear by all accounts to have

been found only in the uppermost parts of the deposits. Shaler was of

the opinion that the buffalo (Allen’s “The American Bison,” p. 234) had

come to the region east of Mississippi River at a very late period,

after the disappearance from Bigbone Lick of the elephants, the

mastodon, and _Symbos_. It seems to the present writer that the presence

of the existing buffalo east of the Mississippi only after the passing

of the Wisconsin ice-sheet is quite certain; but that it came only after

the extinction of the great proboscideans is hardly to be sustained. In

many localities over the country remains of all three species have been

found in swamps overlying the Wisconsin drift. In 1890 (Amer.

Naturalist, vol. XXIV, p. 953), Professor Lucien Underwood described a

fine skull of the American buffalo which had been found in making a

sewer at Syracuse, New York. Underwood stated that it had been found in

black muck, at a depth of 10 feet; but Mr. John Cunningham,

superintendent of grounds at the university, who saw the place and

secured the skull from the laborer who encountered it, told the present

writer that the depth was 17 feet. It would seem that that bison had

lived on the shores of Onondaga Lake not long after the Wisconsin

glacier had withdrawn from the place.

We do not know under what geological conditions the type of _Bison

latifrons_ was found; but it pretty certainly came from post-Illinoian

deposits, probably Sangamon, along possibly Woolper’s Creek in Boone

County. Proboscidean remains have been reported from the Kentucky side

of the Ohio in the region of Cincinnati, but it would be hazardous at

present to assign them a geological age. The same may be said about the

mastodon remains found in digging the canal around the falls, although

the low level along the river seems to indicate the Late Wisconsin.

A collection, forming probably two farm-wagon loads, was made several

years ago at Bluelick Springs, by Mr. Thomas W. Hunter. The springs

having failed, Mr. Hunter undertook to dig down and restore the flow. In

this he failed, but he did find great quantities of bones, mostly those

of the mastodon, but also of elephants, buffaloes, and a few others (p.

129). There were about 100 mastodon teeth, many tusks, and large pieces

of these; and of these pieces about 20 had been planed off so as to be

flat on one or on two sides, as if they had lain in the bottom of a

stream and the water and sand had worn them down on one side and then

the tusks had been turned over and undergone a planing of the opposite

side. Among the bones were two ungual phalanges of _Megalonyx

jeffersonii_ (p. 44), and remains of the elk (p. 243), and deer (p.

234). To none of the species found there need one assign a higher

antiquity than late Pleistocene; but some might have been older. In

Scott County, between Stamping Ground and Georgetown, there has been

found, in the bottom of an old sink-hole, a part of a lower jaw with

teeth of _Tapirus haysii_ (p. 210). The time of existence of this animal

is to be regarded as lying somewhere back of the Wisconsin glacial

stage. With this jaw, Professor Arthur M. Miller sent to the writer some

pieces of jaws of _Tapirus haysii_ (p. 210) which had been found in an

old stream-deposit at Yarnallton, Fayette County. From a fissure filled

with calcite, at Monday’s Landing, Mercer County, there has been sent to

the writer, by Professor Miller, a molar tooth of a horse (p. 202).

Nothing more can be said of this horse than that it is older than the

Wisconsin stage. It may be as old as the first interglacial.

About 5 or 6 miles below Henderson, on Ohio River, many years ago,

considerable parts of the skeleton of _Megalonyx jeffersonii_ were found

(p. 44). With them were reported to have been discovered antlers and

bones of the deer (p. 234). A description of the locality was sent to

Joseph Leidy and published by him in his work on ground-sloths (Smiths.

Contrib. Knowl., vol. VII, art. 5, p. 7). The bone-bed lay at an

elevation of only 5 or 6 feet above an ordinary stage of low water. It

was composed of a ferruginous sand and contained various species of

fresh-water mollusks and stems and limbs of trees. This was underlain by

a bluish clay, while above it, rising 40 or 50 feet, were beds of

siliceous earth and widely spread marls. Neither the geology of the

place, so far as the writer knows, nor the history of the animal

requires us to believe that the geological age is beyond that of the

Late Wisconsin or Wisconsin. However, a short time before, near

Evansville, Indiana, at the mouth of Pigeon Creek, and apparently only

about 10 miles away from where Owen found megalonyx bones, there had

been discovered by Frances A. Lincke, and described by Leidy (Proc.

Acad. Nat. Sci., Phila., vol. VII, 1854, pp. 199–200), a collection of

vertebrate fossils. This included remains of megalonyx (p. 32), a

cervical vertebra of a bison (p. 257), a vertebra of a horse (p. 186), a

tooth of _Tapirus haysii_ (p. 203), and a part of the upper jaw of the

wolf known as _Ænocyon dirus_ (p. 204). The horse was most probably

_Equus complicatus_, while the bison was probably one of the extinct

species. The wolf is regarded as being the same as that so abundantly

found in the collections made at Rancho La Brea, near Los Angeles. The

writer regards the fauna as belonging to the Sangamon, unless it is

still older. The specimens were found sticking out of the river at low

water, and it becomes quite probable that the Henderson beds and bones

are of the same age as those at Evansville.

As mentioned on another page (p. 223) it is probable that the fine skull

of _Platygonus compressus_ that was sent many years ago to the Academy

of Natural Sciences of Philadelphia by Dr. Samuel Brown, of Lexington,

Kentucky, and described by Leidy (Trans. Amer. Philos. Soc., vol. X, p.

331, plates XXXV-XXXVII) had been found somewhere in Rock Castle County.

It counts as another product of the caves which abound in the Alleghany

range of mountains.
