In her ongoing series Mortifera (Latin: dead/deadly animals), artist Julie Anne Mann creates strange new creatures. With approximately 30 different species to date, Mann reconfigures the bones of common animals into mutant or hybrid creatures. From Mann's website:
Some are purely animal, using a Frankensteinian approach of multiple parts from different donors, while others are the possible results of crossbreeding between animal/flora. Blending traditional science and fantasy it is difficult to discern whether they are extinct animals undiscovered from the past or the future of animals to come. Existing in a netherworld of what is possible or possibly lost these new species, constructed from remnants of the dead, present a somber view of a failing planet, but also remind us of the transient, ephemeral quality of nature.
