[The patterns of elongation of the anterior part of the body of limbless squamata].
The interpretation of original features of the aortic trunks showed by subterranean limbless Squamata allows to propose a hypothesis about a particular pattern of elongation regarding the anterior part of these Reptiles. The comparative morphological data supplies some arguments to the idea of the breaking of the topographical link between "scapular level - heart level" and the insertion of a new "precardiac" region which produces a backward displacement of the heart.
