The world’s largest dinosaur skeleton is back on show with other spectacular remains in Berlin’s Natural History Museum after decades of neglect of a building damaged by bombing in the Second World War. Its reappearance marks the highlight of a 128 million euro renovation project to repair the building. The skeleton, of a Brachiosaurus, which is more than 13 metres high, almost reaches the glas...

THIS work is part of a comparative study of the histological and cytological distribution of alkaline phosphatase in developing teleost and elasmobranch fishes, made with a view to throwing some light on the mechanisms involved in calcification and ossification. Whereas the adult mammalian skeleton is almost completely ossified, in the lower vertebrates cartilage persists side by side with bone...

We present the development of the notochord of the Atlantic salmon (Salmo salar L.), from early embryo to sexually mature fish. Over the salmon's lifespan, profound morphological changes occur. Cells and gross structures of the notochord reorganize twice. In the embryo, the volume of the notochord is dominated by large, vacuolated chordocytes; each cell can be modeled as a hydrostat organized i...
