Dinosaur clutch sizes

Been thinking about reproductive strategies lately and it struck that
the upper limit on clutch size for living amniote endotherms seems to
be about 12, and also to decrease with increasing body size.  In
contrast, living amniote ectotherms seem to have an upper limit of
100+, increasing with increasing body size.  I'm not entirely sure
that metabolism has a direct causal role in limiting clutch size, but
it could be one of the costs of endothermy...

Would anyone like to comment, and/or supply some data of the range of
clutch sizes for dinosaurs and the relationship to body size?
