The technofossil record of humans

 

Can you spot the techno fossil?

Zalasiewicz, J., Williams, M., Waters, C.N., Barnosky, A.D. & Haff, P. (2014) The technofossil record of humans. The Anthropocene Review, 1, 34-43.

An interesting research article introducing a stratigraphy (technostratigraphy) for and within the Anthropocene, stratigraphic markers are defined as “fossils” left behind by humans (technofossils); for example Iron Age tools from around 1000 BC. The article is driven by the need to:

  1. characterise the deposits, and
  2. date and correlate strata,

of (and within) the Anthropocene in a similar manner to other periods of geological time. By using technofossils from the different stages of homonid technological development Zalasiewicz et al. argue that a chronology can be developed and applied to the Anthropocene concept. Furthermore, Zalasiewicz et al. provide examples of how technofossils, such as pottery and mobile phones, could be used to produce a high resolution (sub-centennial) dating and correlation of strata; so far an unreachable target for other periods of geological time. The paper provides a thought provoking insight the definition of strata throughout geological time, and a novel technique into how this could be done in the Anthropocene.
