Dear Dr. Wagner, I've the Taquet's and Paul's Ouranosaurus reconstruction
but there're no ossified tendons in the dorsals, sacrals or caudals, for me
this is the first time that I've see a Ouranosaurus reconstruction with
ossified tendons as that mention by HP Aspidel in the Bailey web-page.
However, Taquet in his original description, about the dorsal vertebrae
"A network of intertwined ossified tendons would have been applied to the
neural spines as in Iguanodon. But in the case of the skeleton of
Ouranosaurus nigeriensis described here, the pieces were slightly
disarticulated and the excavation only yielded several fragments of ossified
tendons. The lateral surfaces of the neural spines, smooth up to the 10th
dorsal vertebra become afterwards rugose, marked by raised osseous ridges
which are the remains of the ossified tendons or their attachments".
