Lissamphibian remains are relatively abundant in Lano and consist of about 200 isolated bones.
(1990) provided a preliminary list of the Lano vertebrates, including actinopterygians, lissamphibians, squamates, turtles, crocodyliforms, dinosaurs, pterosaurs, and mammals from the continental deposits, and selachians from the marine beds.
The estimated body size ranges from less than 100 g for lissamphibians and mammals to about 3-4 tons for the largest dinosaur.
At least 37 continental vertebrate taxa are known in the Lano 1 and 2 sites, including actinopterygians, lissamphibians, lepidosaurs, turtles, crocodyliforms, dinosaurs, pterosaurs, and mammals (see Table 1).
Lano enlarges our knowledge of the latest Cretaceous faunas: it includes one of the oldest records of both Salamandridae and Palaeobatrachidae lissamphibians in the world (Duffaud and Rage, 1999), and one of the oldest records of amphisbaenians or anguids in Europe (Rage, 1999).
The Lano assemblage is composed of nearly 40 vertebrate species (i.e., actinopterygians, lissamphibians
, lepidosaurs, turtles, crocodyliforms, dinosaurs, pterosaurs, and mammals), making it one of the most diverse associations hitherto known for this age in Europe (see Csiki-Sava et al., 2015).
Although the cells generally emerge after neural tube closure, emigration in some species is initiated from still-open neural folds prior to completion of neurulation, as is the case in anuran lissamphibians
and mammals (for review, see Baker and Bronner-Fraser, 1997).
