LinkThis covers small paragraphs talking about Opalized Fossils, Spinosaurus Mirabilis, and Haolong. I am researching it and want to yap about it, each subject will have its own comment.
Opalized Fossils are caused by silica rich water replacing natural remains of previously alive organisms, turning bone, shell, and tissues into opal. The opal can either be Precious Opal or Potch. A very specific process is needed for Opalization, and it takes millions of years to do so.

LinkSpinosaurus Mirabilis is the second Spinosaurus to be found in over 100 years (106, I think?) It was said to be more in-land, as opposed to its familiar, the Spinosaurus Aegyptiacus. Mirabilis stood out for it's unusually large crest, which measured over 1.8ft tall. Mirabilis is said to have roamed some 95 million years ago in the Cretaceous period.

LinkHaolong is a Hadrosaurid Ornithopod from the Early Cretaceous in the Yixian Formation of Liaoning in China. Haolong is the only one in its genus.
When unearthed, it was found to have keratin quills like that of a porcupine, used for defense, thermoregulation, and tactile structure.
