Challenges of the minimum postmortem interval (PMI) estimation in forensic scenarios: Is dental histology an alternative?
Leg Med (Tokyo)

University of São Paulo, School of Dentistry of Ribeirão Preto, Department of Basic and Oral Biology, Ribeirão Preto, SP 14040-904, Brazil. Electronic address:
Postmortem interval (PMI) estimates the time since death. Teeth are perennial elements capable of remaining intact in taphonomic environmental circumstances. The objective was to evaluate the feasibility of estimating the minimum postmortem interval (PMI) through histological analyses of dental tissues exposed to burial and drowning conditions, simulating common scenarios in forensic practice.

Article Synopsis
- Researchers analyzed a Late Pleistocene ground sloth tooth from Brazil, previously thought to show signs of human modification through basic optical observation.
- They employed advanced imaging techniques like scanning electron microscopy and synchrotron X-ray fluorescence to differentiate between human and natural marks on the tooth.
- Their findings indicate that the tooth exhibited intentional human modifications, emphasizing the importance of using sophisticated imaging methods to study potential human impacts on fossil remains.
Virtual reconstruction of the Canis arnensis type (Canidae, Mammalia) from the Upper Valdarno Basin (Italy, Early Pleistocene).

Taphonomic deformation, whether it be brittle or plastic, is possibly the most influential process hindering the correct understanding of fossil species morphology. This is especially true if the deformation affects type specimens or applies to or obscures taxonomically diagnostic or functionally significant traits. Target Deformation, a recently developed virtual manipulation protocol, was implemented to address this issue by applying landmark-guided restoration of the original, deformed fossils, using undeformed specimens (or parts thereof) of the same species as a reference.

Biased skeletal part representation is a key element for making inferences about transport decisions, carcass procurement, and use patterns in anthropogenic accumulations. In the absence of destructive taphonomic processes, it is often assumed that the abundance of different anatomical portions represents selective transport and discard patterns of human groups. Because body parts may be transported for specific products such as meat, marrow or grease, a pattern that usually attracts attention in many archaeological sites is the low proportions of appendicular epiphyses.

Department of Geological Sciences, Stockholm University, Stockholm, Sweden; email:
Microbialites provide geological evidence of one of Earth's oldest ecosystems, potentially recording long-standing interactions between coevolving life and the environment. Here, we focus on microbialite accretion and growth and consider how environmental and microbial forces that characterize living ecosystems in Shark Bay and the Bahamas interact to form an initial microbialite architecture, which in turn establishes distinct evolutionary pathways. A conceptual three-dimensional model is developed for microbialite accretion that emphasizes the importance of a dynamic balance between extrinsic and intrinsic factors in determining the initial architecture.
