I am not sure. The suborder Ankylosauria has two major families,
Ankylosauridae and Nodosauridae. One has a tail club, but no
lateral spikes. The other has lateral spikes but no tail club.
I do not remember which is which. (Euoplocephalus is apparently
also in Ankylosauridae, so it will be the same in this respect).

One main reason: the known skeletons of Ankylosaurus are less complete.

Perhaps, I really need to check my references at home on this.
The peace of God be with you.
