Spicomellus from middle Jurassic (168 – 165.3 million years ago), is now the oldest described Ankylosaur.
Ankylosaurs are famous for their defensive armor, with blunt tail-clubs. However, Spicomellus was instead very spiky all over it's body, likely for display.

How these relate to each other and to living ungulates is uncertain, but we do have molecular evidence from some, which puts these as relatives of Perissodactyla (horses+rhinos+tapirs).

Not just the fact that spent nuclear fuel waste is small-volume & contained. The fact that it's solid means it tends to stay in place (unlikely to get on or inside you and cause harm).
In contrast, we are all constantly exposed to fossil fuel waste, entering our bodies with every breath we take.

Climate change is a clear and present danger of global scale with a wide range of damaging impacts on geologic time scales. Small volumes of spent nuclear fuel can be contained safely in dry cask storage for century+ time scales. Let's focus on the former not the latter for now. Cool? Cool. 🔌💡
