And that path, it turns out, was extraordinarily convoluted.
was one of the ankylosaurs—a group of tank-like species covered in bony plates. Their skulls and backs were armored. Their were occasionally armored. Even the nasal passages inside their skulls were lined with bone,preserving these delicate structures, usually lost to time.
