Several species of metriorhynchids are known from the Mörnsheim Formation (
Solnhofen limestone, early Tithonian) of
Bavaria, Germany:
Rhacheosaurus gracilis,
Dakosaurus maximus,
Geosaurus giganteus and
Cricosaurus suevicus. It has been hypothesised that
niche partitioning enabled several species of crocodyliforms to co-exist. The top predators of this Formation appear to be
D. maximus and
G. giganteus, which were large, short-snouted species with serrated teeth. The long-snouted
C. suevicus and
R. gracilis would have fed mostly on fish, although the more lightly built
Rhacheosaurus may have specialised towards feeding on small prey. In addition to these four species of metriorhynchids, a moderate-sized species of
Steneosaurus was also contemporaneous. ==References==
