I'm not getting much useful done today.
One of the reasons that so little is known about the Aardvark is that this amazing creature is mainly nocturnal and solitary
Aha! http://www.aardvark-world.org.uk/
Penelope, Aardvark-World's very own pet aardvark. Her name was suggested by Suzie Buckley and chosen from hundreds of suggestions sent in during 1998 to our "Name the Aardvark" competition. Congratulations Suzie, your name will be seen by the thousands of people who visit Aardvark-World now and in the future.

Penelope will be making guest appearances on various pages in our website at different times, and will generally have fun, frolicking in the background of our pages, and popping up where she's least expected!
A new species of Orycteropodidae (Mammalia, Tubulidentata) in the Mio-Pliocene of northern Chad
THOMAS LEHMANN1*, PATRICK VIGNAUD1, ANDOSSA LIKIUS2 and MICHEL BRUNET1
A new species of fossil Tubulidentata has been found by the Mission Paléoanthropologique Franco-Tchadienne in Northern Chad. It is the first fossil Orycteropodidae (aardvark) from the Mio-Pliocene of Central Africa. The new taxon, Orycteropus abundulafus sp. nov., is considered in the framework of the available Orycteropodidae fossil record. The Chadian specimen is characterized by the highest dental robustness index among all Tubulidentata, the presence of crests on the pterygoid, the triangular-shaped olecranon fossa and the reduction of the deltoid crest. All of these characters are linked to a less fossorial animal that had a tougher diet. This new African species is closer to the Eurasian O. gaudryi than to any other Tubulidentata. Together they form a clade distinct from that which includes O. afer. This is the first evidence of a relationship for aardvarks between Africa and Eurasia. An initial step is made towards revision of the phylogeny of the order. © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society, 2005, 143, 109–131.

Comments Aardvarks are shy, solitary and completely nocturnal. They sleep in burrows by day and emerge to dig for termites after dark. This one was found by spotlighting on open grasslands.
