Attempt to reconstruct body stature basing on circumferences of long bones in fossil body remains.

Studies were conducted on long bones from Middle Ages row cemetery in Milicz (Wrocław voivodship). Basing on measurements of trunc length in humerus, radius, ulna, femur, tibia and fibula as well as on measurements of circumferences of the truncs, simple correlation coefficients were calculated. The correlation coefficients were used to formulate regression equation permitting to reconstruct bone length from corresponding circumference in cases when epiphysis was destroyed. When applied appropriately, the method may be used to reconstruct length of long bones and the entire stature of extinct population members.

[Microstructure of fossil mammalian bones from the Rixdorfer Horizon of Weichsel-Kaltzeit at Niederlehme near Königs Wusterhausen (Brandengurg)].

The structure is reported of bones of glacial-period mammals, which were found in 1973 to 1989 in gravel-sandy soil of the fossiliferous layer "Rixdorfer Horizont" at Niederlehme near Königs Wusterhausen. The findings, probably, date from one of the interstages of the glacial period "Weichsel-Kaltzeit" before the stage "Brandenburger Stadium". Their embedding took place more than 20,000 years ago. Changes of the deposit of bones and teeth from older sediments are not to exclude in the finding place Niederlehme. In the collection of findings with 102 skeletal parts are to define following species: Mammuthus primigenius, Coelodonta antiquitatis, Equus sp., Bison priscus, Megalocerus giganteus, Cervus elaphus, Rangifer tarandus and Canis lupus. A trajectorial direction of the trabecula in the substantia spongiosa is evident. There are also specific channels of blood vessels with different diameters. This channels have completely closed bone-wall (with a central venous sinus of diameter 5 to 10 mm) or in little vessels (diameter 1 to 3 mm), we have found many apertures to the rooms of the substantia spongiosa. The microscopical investigation of bones of Mammuthus primigenius has shown Havers' channels and perforating channels, Havers' systems and lacunae osseae.

Nematode larvae in fossilized animal coprolites from lower and middle Pleistocene sites, central Italy.

Nematode larvae were found in mineralized animal coprolites collected in lower and middle Pleistocene sites, central Italy. Coprolites collected in 4 paleontological sites dated from 1.5 million years to 30,000 years ago were identified as of Hyaenidae (Mammalia, Carnivora). Checklists available for present-day Hyaenidae did not permit identification of the larvae found. This is one of the most ancient parasite findings in coprolites.

Hominid fossil sample from Kanjera, Kenya: description, provenance, and implications of new and earlier discoveries.

Anatomically modern hominids were first collected from Kanjera, Kenya, by L.S.B. Leakey in the 1930s. Their apparent association with an archaic fauna was quickly challenged, throwing their age into doubt. Further unpublished hominid fragments were collected in 1974, 1975, 1981, and 1987. We review the context and morphology of the entire hominid sample. A minimum number of five individuals is represented by both cranial and postcranial elements. Several individuals have thickened cranial vaults, a characteristic originally thought to reflect their great antiquity. Vault thickening resulted from diploic expansion and may have been a response to acquired or inherited anemia. The entire hominid sample postdates the Kanjera Formation, deposited from the early into the middle Pleistocene. Most of the sample was derived from the black cotton soil capping the stratigraphic column. The morphology and context of the Kanjera hominids is consistent with human skeletal remains from nearby Holocene sites. Hominid 3 was probably an intrusive burial into an early Pleistocene bed.
