Tre nye mammutfunn i Norge = Three new finds of mammoth in Norway.

Three new finds of fragments of Mammoth have been made in Norway during the last 5 years, making the total number of Norwegian mammoth-finds to be eleven (two bone-fragments, three tusks and 6 molars). All the new finds, corresponding to all the earlier, have been made in the Gudbrandsdalen's draining-system. The first new fragment was found in 1955 near Lillehammer, and consists of two pieces from the left shoulder-blade of a large mammoth. The bones were discovered during the digging of a well in clay about 8 ms below the surface of a terrace about 60 ms above the level of lake Mjøsen near the farm Søre Ål. It is the first fragment of a mammoth-bone discovered in Norway. The second find was made in 1959 in stratified gravel about 7 ms below the surface in a gravel-pit about 20 ms high, on the west side of river Lågen immediately north of Fåvang railway-station. It is a fragment of probably the 6th, 7th or 8th thoracic vertebrae of a fullgrown mammoth. The piece represents a larger part of the neural spine and the "roof" of the neural arch. It is the second mammoth-bone fragment known from Norway. The third find, made in 1961, lay in stratified fine gravel almost 4 ms below the surface on the west side of Lågen, about 30- 40 ms above the level of the river, somewhat north of Kvam railway station. It is a fragment of a large and well-preserved, but partly damaged third lower left molar (M3). (Pl. Il; Fig. 5). On the whole surface 12 enamel-lamellae can be seen, furthermore traces of 3 additional, strongly worn lamellae on the front part of the tooth. The back part of the tooth is broken off, but one may suppose that at least 11- 12 lamellae were originally developed in this part. This makes the total number of enamel-lamellae in our tooth to be about 26 - 27 - the number known from the largest M3 in mammoths. All the 11 Norwegian mammoth-fragments are, as mentioned above, found in the Gudbrandsdalen- and Mjøsa-districts, forming a natural draining-system. Thus it seems rather improbable to suppose that these concentrations of mammoth-finds are accidental. The most plausible explanation may be that during the last glaciation in the higher parts of Gudbrandsdalen the deposits from the last interglacial period were preserved in a relatively large extent. The thickness of the ice in these parts of the country was apparently not especially great, as the climate here was rather dry. Also the force of the erosion of the ice was not especially strong, as the district was situated not far from the iceshed-line. During the post-glacial time the melting water has probably eroded most of these interglacial deposits and transported the mammoth-fragments they contained lower down the valley. The greatest part of these fragile fossils were completely destroyed, some, however, became deposited in the stratified gravels, sands or clays in the river or lake-deposits.

I løpet av de siste 5 år er det kommet tre nye norske mammutfunn til Paleontologisk museum. Det første stammer fra Lillehammer og ble funnet høsten 1955, men kom først til museet vinteren 1956. Jeg har omtalt det ganske kort i en artikkel i (A. HEINTZ 1956). Det andre ble gjort ved Fåvang i 1959, det ble sendt til museet i 1961. Begge disse funn er rester av skjelettet. Det siste funn ble gjort i 1961 ved Kvam og er igjen en stor og godt bevart kinntann. Med disse tre siste rester er antallet av mammut-funn i Norge steget til 11.
