Starting off

Hi all. I just started with this blog. For the moment I am in Mexico on a field trip an will, get in more information soon. I am a museum person. The institution is named “Staatliches Museum für Naturkunde Karlsruhe” (Natural History Museum Karlsruhe), which is one of the oldest natural history museums in the world.

    Welcome, Dino!

    I gather you have suggested that sauropods might have had air bladders stacked under their necks to help provide support. I got there by wondering how to get the cervical ribs into tension, and contemplating the empty space behind/below omeisaurus’s skull. How did you come to it? If it’s right, a finite-element analysis of a deeply pneumatic cervical vertebra should show it had to have been in tension too.

    Hi Nathan,

    Daniela Schwarz and I modelled a possible sytstem of air sacks as a part of a pneumatic system in the neck of sauropods. We hypothesised, wether or not an pneumatic support of a segmented chain beam would be possible and constructed a simple model and it worked. With an overlapping system of cervical ribs as a compressive system further bracing mechanisms are not necessary. For the studies, Daniela provided hi res CAT scans which would work as a digigtal base for ANSYS and ABACUS. We will probably go for this.
