Three models, three very different animals, three methods:
Anomalocaris, sculpted in fimo according to fossil drawings, 6 cm long
Hesperornis, digitally distorted from a recent bird skeleton and Tyrannosaurus skull, 3d printed, 9cm long.
Hydrodamalis, skull digitally distorted from a dog skull, postcranial plywood and putty like my whales, 38 cm.
