Calcar

Calcar

The calcar, also known as the calcaneum [http://www.earthlife.net/mammals/bat-anatomy.html The Anatomy of Bats ] ] , is the name given to a spur of cartilage arising from inner side of ankle and running along part of outer interfemoral membrane in bats [http://www.earthlife.net/mammals/bat-anatomy.html The Anatomy of Bats ] ] The Handbook of British Mammals (ASIN B000WPL1CO)] , this is to help spread the interfemoral membrane [http://www.si.edu/Encyclopedia_SI/nmnh/batfacts.htm Encyclopedia Smithsonian: Bat Facts ] ] , which is part of the wing membrane between the tail and the hind legs.

This membrane can form a basket or pouch to help catch and hold insects captured in flight [http://www.earthlife.net/mammals/bat-anatomy.html The Anatomy of Bats ] ] . The oldest known ancestor to present day bats, Icaronycteris index, apparently did not have a calcar or spur as evidenced by fossil remains.Ontogeny, Functional Ecology, and Evolution of Bats (ISBN 978-0-52-162632-3)] .

Calcar (Femorale) also refers to the dense, vertically orientated bone present in the posteroemedial region of the femoral shaft under the lesser trochanter of the femur.
