Mounting is most of what makes these models really come to life and after a lot of trial and error I found some easy solutions. 

I’ve found using 1/4” steel rods to connect the models to boards from Lowe’s or any hardware store is best. The rods are easily cut with a hacksaw. Mounting them to the actual board though I use this flange generator to 3D print a custom piece:

I can share my settings if it helps, I would ultimately scale the flange to 105-107% in your slicer so the steel rods easily slides in. 

Specifically for the inhuman species full size velociraptor I recommend trying to find some 1/8” ALUMINUM pipe if possible. The steel running through the spine was a nightmare to try and bend and ended up being so heavy it needed all those supports. The entire thing needs quite a bit of CA glue to actually stay together. I know the design recommends some 4mm rod in other places but the only place I have metal in that model is the spine and supports. The allosaurus (Big Al Two) head I attached the jaw using a cheap 3D printing pen and further fused it with a soldering iron.  Most smaller models can easily be glued together with CA glue. So far only the allosaurus needed that extra step to attach the jaw. Every time I use CA glue I also use baking soda as an activator which has worked well. 

I just wanted to share what I’ve learned so far because 3D printing specimens is incredibly rewarding to learn more about their anatomy, and they look really cool.
