Forensic Botany and Palynology: Grass Phytoliths, Gastric Contents, Root Growth and Grave Indicators

This mock test explores four applied domains of forensic botany that converge at death-scene investigation and evidence interpretation. Questions cover grass phytolith analysis and transfer, the forensic examination of gastric plant matter and stomach contents, root-penetration models for grave dating, vegetational disturbance signatures over clandestine burials, and the use of plant colonisation sequences on surface-deposited remains as post-mortem interval indicators. Each topic demands the ability to connect botanical biology to evidential interpretation and to distinguish between near-neighbour methods and marker types.

This test is designed for students, MSc and BSc learners, and practitioners of forensic Forensic Botany and Palynology who are applying botanical evidence to casework scenarios. The questions assume familiarity with basic plant anatomy, decomposition ecology, and forensic evidence standards, and they draw on current literature in phytolith science, forensic taphonomy, and clandestine grave detection.

Topics covered:

• Grass phytolith morphology and forensic transfer analysis
• Phytolith extraction and reference-collection methods
• Gastric plant fragment identification and digestion timing
• Stomach content evidence in last-meal reconstruction
• Root-penetration rate models and grave-dating applications
• Vegetational disturbance indicators over clandestine graves
• Plant colonisation sequences as PMI indicators on surface remains
• Lichen and moss growth as minimum PMI markers on bone

Mastery of these topics underpins botanical contributions to clandestine grave investigation and post-mortem interval estimation. Allow 30 minutes.
