#AmReading: The Nature of Life and Death: Every Body Leaves a Trace by Patricia Wiltshire

“We all leave our marks on the environment, but the environment leaves its mark on us too…”

Turns out you’ll never get away with the perfect crime if this lady has anything to say about it. She’s a forensic ecologist, botanist, and archeological palynologist.

What does that even mean?!

Patricia Wiltshire is one of the leading experts in the study of plants, pollen, fungi, spores, and how they provide crucial evidence in criminal investigations. Her book weaves science lessons with personal anecdotes, explaining how these innocuous materials have determined the fates of many a court case.

I had absolutely no clue how specific the evidence could get. Locations can be pinpointed with unnerving accuracy. Witness accounts can be proven or disproven. Missing bodies can be found based off microscopic debris on the gas pedal of a car.

This is a great book for anyone who wants to get into the weeds (see what I did there?) of forensic and plant related minutiae. It’s VERY sciencey. Be prepared to read pages about the differences between types of pollen, but the overall picture is fascinating. The author also relays the events of her life that led her into such an unusual field (that’s another pun). Some of her stories are a bit gruesome, but if you’re reading forensic type books for fun, that’s probably what you expect.

journals.plos.orgVegetation and climate change at the southern margin of the Neo-Tethys during the Cenomanian (Late Cretaceous): Evidence from EgyptChanges in terrestrial vegetation during the mid-Cretaceous and their link to climate and environmental change are poorly understood. In this study, we use plant macrofossils and analysis of fossil pollen and spores from the Western Desert, Egypt, to assess temporal changes in plant communities during the Cenomanian. The investigated strata have relatively diverse sporomorph assemblages, which reflect the nature of parent vegetation. Specifically, the palynofloras represent ferns, conifers, monosulcate pollen producers, Gnetales, and a diverse group of angiosperms. Comparisons of both, dispersed palynoflora and plant macrofossils reveal different characteristics of the palaeoflora owing to a plethora of taphonomical and ecological biases including the depositional environment, production levels, and discrepancies between different plant organs. A combination of detailed records of sporomorphs, leaves, and charcoal from the studied successions provide new understandings of the palaeoclimate and palaeogeography during the Cenomanian and Albian-Cenomanian transition in Egypt. The mixed composition of the palynofloral assemblages reflects the presence of different depositional situations with a weak marine influence, as evidenced by a minor dinoflagellate cysts component. The local vegetation comprised various categories including herbaceous groups including ferns and eudicots, fluvial, open environments, and xeric arboreal communities dominated by Cheirolepidiaceae and perhaps including drought- and/or salt-tolerating ferns (Anemiaceae) and other gymnosperms (Araucariaceae, Ginkgoales, Cycadales, and Gnetales) as well as angiosperms. The presence of riparian and freshwater wetland communities favouring aquatic and/or hygrophilous ferns (of Salviniaceae and Marsileaceae), is noted. The wide variation of depositional settings derived from the palynological data may be attributed to a prevalent occurrence of producers in local vegetation during the early Cenomanian of Egypt. For the purpose of this work on the studied Bahariya Formation and its equivalent rock units, where iconic dinosaurs and other fossil fauna roamed, we attempt to improve the understanding of Egypt’s Cenomanian climate, which is reconstructed as generally warm and humid punctuated by phases of considerably drier conditions of varying duration.
