Odvození paleopotravy Ursus spelaeus ROSENMÜLLER et HEINROTH použitím analýz izotopů uhlíku zubu z jeskyně Tmavá skala (Slovenská republika)Článek v PDF
Paleodiet inferred from Ursus spelaeus ROSENMÜLLER et HEINROTH tooth from Tmavá skala cave (Slovak Republic) using carbon isotope analyses
Isotopes of carbon were employed in the study of Ursus spelaeus second upper molar M2 from Late Würm bear cave Tmavá skala (Little Carpathians, Slovak Republic). Samples of enamel and dentine were used for the analyses. Variations in the carbon isotope ratio (13C/12C) were used to examine the paleodiet. The δ13C of investigated tooth is -11,8 ‰ for dentine and -16 ‰ for enamel. This indicates that the diet of Ursus spelaeus was dominated by C3 biomass. These values suggest a forested habitat.
