TI  - New formulas to estimate age at death in Maya populations using 
      histomorphological changes in the fourth human rib*.

AB  - This study develops new histomorphological algorithms for Maya populations' human 
      ribs and tests the applicability of published algorithms. Thin sections from the 
      fourth rib of 36 individuals of known age were analyzed under polarized light 
      microscopy. Osteon population density (OPD, the concentration of intact and 
      fragmented osteons per mm(2)), cortical area (CA), and osteon size (OS) were 
      recorded. Seven algorithms were calculated, using all combinations of variables, 
      and compared to the performance of published formulas. The OPD-based formulas 
      deviate from the known age 8.7 years on average, while those from OS and CA 
      deviate between 10.7 and 12.8 years. In comparison, our OPD-based algorithms 
      perform better than the one by Stout and Paine and much better than Cho et al. In 
      conclusion, algorithms should be developed using OPD for different ethnic groups; 
      although Stout and Paine's can be used for Maya and maybe Mesoamerican 
      individuals.
