'THE CROCODILE IN A TREE'

The exhibition 'Krokodil im Baum'/'Crocodile in a tree' was an outreach activity of our group aiming at transmitting the notion of evolutionary trees to understand biodiversity and its origin, using crocodylians as main subject. Prof. Marcelo Sánchez used crocodylians as previous research results published by Scheyer et al. (2013) as the scientific basis for an AGORA grant from the Swiss National Science Foundation. The realization of the exhibit was coordinated by Life Science Zurich.

Following the closure of the special exhibit in the Zoological Museum of the University of Zurich, a virtual tour though the exhibit was made to digitally preserve the exhibit as a source of information for scholars and the public. A German and an English version of the virtual tour are available on the PIMUZ website. Image credits: Jorge Gonzalez
