'''Mutual Climatic Range''' ('''MCR''') is a method of determining the past climate at an archaeological site by examining the tolerances of a range of species found there. One method is to find the average temperatures in January and July by looking at the modern distribution of beetle species found on the site.<ref>{{cite book|first= Nick|last= Ashton |title=Early Humans |authorlink= |publisher=William Collins |location = London |year=2017|page=316 |edition= |isbn=978-0-00-815035-8 }}</ref> Another application is to look at the tolerances of plant species to determine 'summer warmth and dryness' and 'wetness and winter warmth'.<ref>{{cite journal|url=http://jgs.geoscienceworld.org/content/156/2/381|title=A mutual climatic range method for reconstructing palaeoclimate from plant remains|journal=Journal of the Geological Society|date=1 March 1999|first1=J.

The technique was developed in the 1980s, and a newer one first published in 2009 which looks at geographical distribution is also sometimes called "mutual climatic range".<ref>{{cite journal|title=The mutual climatic range technique is (usually) not the area of sympatry technique when reconstructing paleoenvironments based on faunal remains|journal=Palaeogeography, Palaeoclimatology, Palaeoecology|publisher=Elsevier|date=15 July 2016|first=R.
