Of course the important thing to note here is that the Fossil mechanic has reverted back to how it was in Gen IV and earlier, with Fossil Pokemon evolving directly from a Fossil Trainer card. See EX Sandstorm's Mysterious Fossil, Majestic Dawn's Dome Fossil, Platinum's Armor Fossil, etc. Starting with Gen V, Fossil Pokemon could only be brought into play with the effect of a their Fossil Trainers; they didn’t evolve directly from them. See Noble Victories's Plume Fossil, Steam Siege's Armor Fossil Shieldon, Tirtouga from Plasma Blast, etc.
Unlike in Gen III and even more in Gen IV, all the current Fossil Pokemon evolve only from Mysterious Fossil rather than their own individual Fossil cards (like Dome Fossil or Armor Fossil). This means you’re limited in how many Fossil lines you can run in a deck since you can only have four copies of Mysterious Fossil. In Gen IV, individual Fossil cards also had unique Poke-Bodies (Abilities), which the old and new Mysterious Fossil cards lack.
Also here’s a funny note: you can evolve this Stage 1 Shieldon into the Stage 1 Bastiodon from Steam Siege. XD
