Abstract
Original and published data on the structure of egg teeth in squamate reptiles and the phylogenetic significance of corresponding characters are reviewed, elaborating A.M. Sergeev’s ideas on the subject. Problems are discussed concerning the use of this character in modern phylogenetic constructions and the necessity of new embryological investigations to resolve the issue concerning the formation of an unpaired egg tooth rudiment in all Squamata except the Dibamidae and Gekkota.
