Dear friends, Human evolution is more easy if we have 3D skull copies but they are very expenssive and I cannot find places that donate the skulls. I was sad about it but... I move my focus and now I am searching for 3D skulls online (animated videos). Until now I know about three good sources and I thank all the people of this list for sharing this information: 1 - http://humanorigins.si.edu/evidence/3d-collection Smithsonian Institute have this tool but it is not working because they are renewing the skull material. I wrote them today asking about when the website will be avaliable again. 2 - http://www.boneclones.net They have animated files of several skuuls but using Adobe Flash Player and Microsoft is planing stop using this tool in Google Chrome in 2020. I wrote today to boneclones asking them to mantain this good option. 3 - https://sketchfab.com They have several skulls online and you can rotate them in several directions. Thanks for all :) Prof. Dr. Júlio Cesar Voltolini Grupo de Pesquisa e Ensino em Biologia da Conservação - ECOTROP. Universidade de Taubaté, Departamento de Biologia. Taubaté, SP. Brasil.
