Despite there being a lot of Kentrosaurus material, and it being well-described, this still proved to be a challenge because it's not all from specimens of the same size. I'm still not 100% convinced that the forelimbs don't need to be scaled up relative to the hindlimbs, but I've left them at the same size as the Berlin composite mount. The other elements seem to check out - and I'll say that I can't replicate the extremely tall body that is extremely short front to back like in some previous reconstructions.
Edit: After some discussion with Heinrich Mallison I've updated the tail spikes. As for the underlying data on the tail spikes, as well as the unresolved issue of where the large body spike goes...there will be more on that later. In the meantime, keep in mind that whether there is a shoulder spike, a hip spike, or some other configurations is not really settled for Kentrosaurus.
