fossil embryos?

From
Date
        Dear all,
Recently in an Upper Ladinian locality in northern Italy we have found some
tiny specimens that we suspect to be embryos of the "nothosaur" reptile
Lariosaurus (adults from the same locality have already been collected and
published). I will greatly acknowledge if someone can suggest recent
literature or advices about the adult/hatchling ratios and sizes in fossil
and/or extant reptiles and related topics. I have already the paper of
Sander on Neusticosaurus embryo (Science, 1988) and the work of Currie and
Carroll on JVP 1984 about Thadeosaurus.
Many thanks in advance, 
Wishes

                                        Silvio Renesto
