Excavation at the Hot Springs Mammoth Site: A Late Pleistocene Animal Trap
Construction work on a housing development in southern Hot Springs, South Dakota, during July 1974 exposed teeth, tusks, skulls, and post-cranial elements of mammoth. These were located in a small deposit of sand within the Spearfish Formation, a red shale of Permian-Triassic age.
The deposit was originally a topographic depression. Prior to construction, it stood as a ridge, the sand and gravel armoring the adjacent shale. It is currently a sandy knob left by the construction work.
Initial excavation during 1974 and 1975 (Agenbroad and Jones, 1975) was salvage and exploratory in nature. The abundant faunal remains from such efforts resulted in a field season from June 13 to July 19, 1976
Clovis Projectile Point Occurrences In Northwestern Nebraska
Two Clovis projectile point finds are reported from the Panhandle of Nebraska (Dawes and Sioux Counties). Both are surface finds and both bear resemblance to finds in Arizona and Oklahoma.
Two recent Clovis projectile point finds from the Panhandle of Nebraska warrent description. The artifacts are in the possession discoverer, Mr. William (Bill) Hudson of Crawford, Nebraska. Both artifacts are surface finds in local areas of bad land topography in Dawes and Sioux Counties. The rarity of Occurrence of this distinctive projectile point in Nebraska, whether surface find or not, makes the discoveries of importance. To my knowledge (Agenbroad, 1971), there are no occurrences of Clovis projectile points, in situ, in stratified sites within the state. At least all published records are a surface finds or recovered from sand screening operations in gravel pits. The significance of Clovis projectile points as time and cultural markers makes record of their occurrence important regardless of the nature of the find.
The two Panhandle points include one complete point and one basal fragment (Fig. 1). The metric data (in mm unless stated otherwise) for the two points are as follows: data for the complete point are given first, that for the basal fragment follow in parentheses: maximum width 29(33), weight in grams 37.6 (-), maximum thickness 9 (5), maximum length 106 (-), distance from base to point of maximum thickness 53 (41), base width 26 (31), depth of basal concavity 5 (6), flute scar 0.30, R. 29 (0.22, R.37), lateral grind L(29) R37, L31, R(39). Both points are of agate.
Comparison of the metric data for these specimens and that for points recovered at classic sites (e.g., Lehncr Ranch, Naco I and II, Murray Springs, Escapule. Arizona; Dent, Colorado; Clovis, New Mexico; and Domebo. Oklahoma) indicate that the Nebraska points readily fall within the range of values for points from classic sites. The greatest affinities of the Nebraska points are with those of the Arizona and Oklahoma sites
Relationships within the Elephantinae using hyoid characters
Results are based on ten hyoid characters of seven proboscidean taxa; four belong to the subfamily Elephantinae. Using PAUP we generated six equally parsimonious trees. The consensus tree yields two polytomies: in the basal polytomy the relationships among Mammut, gomphotheres, Stegodon, and Loxodonta are not resolved; in the other polytomy Palaeoloxodon, Mammuthus, and Elephas are grouped in a cluster. The joining of Palaeoloxodon and Mammuthus has not been suggested previously, and there are ample non-hyoid data of grouping Loxodonta, Elephas, and Mammuthus. For this reason and since a major focus of this study has been to test relationships among Loxodonta, Elephas, and Marnmuthus, we relied on studies of other workers and rearranged the consensus cladogram to unite Loxodonta with other members of Elephantinac (Palaeoloxodon, Elephas, and Marnmuthus). The hypothesis that Mammuthus is more closely related to Elephas than to Loxodonta is more parsimonious (by two evolutionary steps) than when Loxodonta joins Marnmuthus. This finding is provisional and should be retested with additional data, especially with taxa with small sample size, and with specimens of extinct Elephantinae taxa. Results also corroborate other findings that Palaeoloxodon is a bonafide elephant genus; we classify it in the new subtribe Palaeoloxodontina Zhang and Zong [1983. Genus Palaeoloxodon of China. Vertebrata PalAsiatica 21(4), 301-312]. (C) 2007 Elsevier Ltd and INQUA. All rights reserved
