Late Pleistocene spotted hyena Crocuta crocuta spelaea (Goldfuss, 1823) and steppe lion Panthera leo spelaea (Goldfuss, 1810) were top predators in Central Europe. The fossil record (2.303 hyena/1.373 lion bones = ratio 3/1) from 106 cave and open air sites demonstrates comparable associations to modern African hyenas/lions resulting in competition about prey and territory. Cannibalism within extinct spotted hyenas is well documented, including two individual skeletons. Those hyenas produced bone accumulations at dens. Feeding specializations on different megamammal groups are demonstrated for Late Pleistocene hyenas whose prey partly overlaps (e.g., cave bears) with those of lions and wolves. At most fossil sites, 1–3% of the lion remains indicate scavenging of lions by hyenas. The larger Late Pleistocene felids focussed on cervids (reindeers specialization during the high glacial = LGM), on bovids (steppe bison/aurochs), and possibly on saiga antelope and on the cave bear, hunting deep in caves during their hibernations and targeting cubs. The cave bear feeding was the target of all three top predators (lions, hyenas, and wolves) in the Late Pleistocene boreal forests which caused deathly conflicts in caves between them, especially with lions/hyenas and herbivorous cave bears that have no modern analogue.

The Late Pleistocene (MIS 5c-d) Ice Age spotted hyena open air den and bone accumulation site Bad Wildungen-Biedensteg (Hesse, NW, Germany) represents the first open air loess fox/badger den site in Europe, which must have been recycled by Crocuta crocuta spelaea (Goldfuss, 1823) as a birthing den. Badger and fox remains, plus remains of their prey (mainly hare), have been found within the loess. Hyena remains from that site include parts of cub skeletons which represent 10% of the megafauna bones. Also a commuting den area existed, which was well marked by hyena faecal pellets. Most of the hyena prey bones expose crack, bite, and nibbling marks, especially the most common bones, the woolly rhinoceros Coelodonta antiquitatis (NISP  =  32%). The large amount of woolly rhinoceros bones indicate hunting/scavenging specializing on this large prey by hyenas. Other important mammoth steppe hyena prey remains are from Mammuthus primigenius, Equus caballus przewalskii, Bison/Bos, Megaloceros giganteus, Cervus elaphus, and Rangifer tarandus. The few damaged bone remains of a scavenged cave bear Ursus spelaeus subsp. are unique for an open air situation. Abundant micromammal, frog, and some fish remains were concentrated in “pellets” that contain mainly mammoth steppe micromammals and also frog and fish remains that seem to originate from the nearby river/lake.

Punctured extinct cave bear femora were misidentified in southeastern Europe (Hungary/Slovenia) as ‘Palaeolithic bone flutes’ and the ‘oldest Neanderthal instruments’. These are not instruments, nor human made, but products of the most important cave bear scavengers of Europe, hyenas. Late Middle to Late Pleistocene (Mousterian to Gravettian) Ice Age spotted hyenas of Europe occupied mainly cave entrances as dens (communal/cub raising den types), but went deeper for scavenging into cave bear dens, or used in a few cases branches/diagonal shafts (i.e. prey storage den type). In most of those dens, about 20% of adult to 80% of bear cub remains have large carnivore damage. Hyenas left bones in repeating similar tooth mark and crush damage stages, demonstrating a butchering/bone cracking strategy. The femora of subadult cave bears are intermediate in damage patterns, compared to the adult ones, which were fully crushed to pieces. Hyenas produced round–oval puncture marks in cub femora only by the bone-crushing premolar teeth of both upper and lower jaw. The punctures/tooth impact marks are often present on both sides of the shaft of cave bear cub femora and are simply a result of non-breakage of the slightly calcified shaft compacta. All stages of femur puncturing to crushing are demonstrated herein, especially on a large cave bear population from a German cave bear den.

Almost All

The Greenhouse Effect acts to slow the escape of infrared radiation to space, and hence warms the atmosphere. The oceans derive almost all of their thermal energy from the sun, and none from infrared radiation in the atmosphere. The thermal energy stored by the oceans is transported globally and released after a range of different time periods. The release of thermal energy from the oceans modifies the behaviour of atmospheric circulation, and hence varies climate. Based on ocean behaviour, New Zealand can expect weather patterns similar to those from 1890-1922 and another Little Ice Age may develop this century.

New Hypothesis

Khutū was a material derived from an animal used by Medieval Asian peoples in the manufacture of knife handles and as an alexipharmic. Al-Bīrūnī (973–1048) made extensive enquiries into the origin of khutū but reached no definite conclusion. Literary scholars in the first half of the twentieth century identified the walrus and narwhal as probable sources, but in ignoring aspects of the literature on khutū’s appearance and provenance left a number of questions unanswered. We clarify and extend this research and identify further clues to the identity of khutū. We concur that walrus ivory was one source of khutū, suggest that the remains of “Ice Age” mammals may have influenced development of the medieval literature on khutū more than previous investigators realized, and offer a new hypothesis of khutū’s origin.
