 However, this specimen was alternatively reassigned to "Lycorhinus" by Sereno in 2012, which is already known to have possessed tusks and therefore their absence in "Abrictosaurus" may not have been a result of age.In 2005 a small complete fossilized heterodontosaurid skeleton more than 200 million years old was discovered in South Africa.In July 2016 it was scanned by a team of South African researchers using the European Synchrotron Radiation Facility; the scan of the dentition revealed palate bones less than a millimeter thick.
