I went to <a href=" http://www.kirschnergroup.com/stmap_85812.html ">novartis voltaren emulgel 100 g testbericht</a> Preserved among the remnants is evidence of fur and a keratinous spur that jutted from the hind ankle and was probably used to deliver poison to predators. The bones of its middle ear were more primitive, and attached to the jaw as in reptiles. The discovery shows that animals evolved to have fur before the first true mammals emerged. The fur was primarily for insulation, but may also have served a sensory purpose.
