There has been some controversy about alleged tracks from
rhamphorhynchoid pterosaurs--pterodactyloid pterosaur tracks are well
documented and scientifically accepted.

The following news story in French indicates that clear evidence of
tracks left by a rhamphorhynchoid may have been found at Crayssac in
France:

The tracks of a rhamphorhynchoid pterosaur (nicknamed Dimitri) found
at Crayssac are being studied with light projected at a low angle to
bring out the details and are yet to described.

These are reportedly the first confirmed tracks of a rhamphorhynchoid
and show that it walked quadrupedally like a pterodactyloid.
