Unless I am mistaken or there is a typo in the release notes, these should be the Dinosaur/Creature levels they need to be to evolve.
What does everyone think of these new hybrids and will you be able to create Megalogaia & Entelomoth?
Megalogaia = Miragaia (10) + Megaloceros (10)
Entelomoth = Entelodon (15) + Woolly Mammoth (15)
Dilophoboa = Titanoboa (15) + Dilophosaurus Gen 2 (15)
Spinoconstrictor = Spinosaurus (20) + Dilophoboa (20)
