From the sawfish swimming in the oceans today to some of those species that went extinct at the end of the Cretaceous Period, I presented some of our recent work at the Natural History Museum in London. My next Nature Live is scheduled for September 13th 2015.
Our research into conserved genetic pathways in tooth patterning and development now encompasses one of the most basal bony fish -- the american paddlefish. Both sonic hedgehog and Bmp4 play important roles in odontogenesis in this species.

The elongated rostrum of an extinct ray known as Schizorhiza stromeri has been added to the museum's collections.
From the first fossils found in Cretaceous rocks to the species on the brink of extinction today, Monique provides a detailed account of both sawfishes (relatives of rays) and sawsharks (relatives of sharks) and their unique methods of rostral denticle development and replacement.
