The study aims to develop a novel, inexpensive, rapid, and resource-saving maceration technique that does not lead to bone surface changes and allows the study of signs of violence on the bone surface. Pig ribs and femurs were covered in aluminum foil and treated in the oven for 5 h at different temperatures with and without detergent. Additionally, femurs were placed in hot non-boiling water containing household bleach and detergents for 1 h. Examinations using macro photography, stereo and fluorescence microscopy, and micro-computed tomography showed no surface changes after treatment at 100 °C, such as flakes or bone cracks, on the ribs. The femurs showed surface changes after incubation in water, such as roughening.Although recent studies explored using microbial succession during decomposition to estimate the postmortem interval (PMI) and postmortem submersion interval (PMSI), there is currently no published research using aquatic eukaryotic community succession to estimate the minimum postmortem submersion interval (PMSImin). The goals of this study were to determine whether eukaryotic community succession occurs on porcine skeletal remains in a lentic environment, and, if so, to develop a statistical model for PMSImin prediction. Fresh porcine bones (rib N = 100, scapula N = 100) were placed in cages (10'' x 10'') attached to floatation devices and submerged in a fresh water lake (Crozet, VA), using waterproof loggers and a YSI Sonde to record temperature and water quality variables, respectively. In addition to baseline samples, one cage, containing five ribs and five scapulae, and water samples (500 mL) were collected approximately every 250 accumulated degree days (ADD). Nineteen sample cohorts were collected overn increase i
