Okay, but consider:
Someone (probably Hermione) takes Luna to a muggle museum of natural history, in a last ditch effort to convince her that dinosaurs really did exist. They go through all of it: full and partial skeletons on display, fossil imprints of skin textures, a little video about carbon dating, exhibits on the evolution of all life from tiny one-celled sea creatures, bird-hipped vs. lizard-hipped, living giant isopods and coelacanths, the whole spiel about how the dinosaurs aren’t actually completely gone, since some, like the anchiornis and archaeopteryx, were the predecessors from which today’s birds – including every owl in the Wizarding World – evolved.
Luna takes all this in with her usual calm demeanor until the very end, when her eyes seem to grow even more enormous in her face, but doesn’t say anything. After a full minute of Luna’s silent astonishment, her companion prods her for a response. “Of course!” Luna exclaims, “no wonder I’ve never found them. I’ve been going about things the wrong way!” She launches into a lengthy explanation that the records that she and her father have been using for references were copies of copies of copies of absolutely ancient scripts, so in order to find the creatures as described in them, she needed to be looking for fossils.
Luna (with Rolf as her assistant) begins searching through areas of Wizarding Britain, using magical equivalents of the muggle tools she read about at the museum (a variation on Tempus to determine the age of a magical item or creature, Cryptozoam Revelio as a substitute for ground-penetrating radar). She finds the remains of a number of magical creatures from various ages, as well as accidentally uncovering a nest of Knuckers, a relative of the dragon previously thought to be extinct. After this discovery, she and Rolf are given a bit more credence than before, and they gain the support among creature-handlers, especially dragonologists. Because of this, they get access to more regions of the world, and their team grows. Eventually Luna ends up founding the Wizarding Archaeological Society, the first institution to combine both muggle and wizard research methods at a single institution.
On the 50th anniversary of the Society’s founding, they open a museum of their own (”Everything that was, at the WAS!”), to display the various fossils of magical creatures that they’ve managed to locate over the years. Unveiled at the opening ceremonies was what would become the pride of their collection, a diorama of Crumple-Horned Snorkacks in every stage of development, along with details about their habits, average lifespan, and a map of the full range of their habitat at their peak population in the mid-17th century. Their extinction at during the 20th century was attributed to rising global temperatures, as their most flourishing period coincided with the coldest years of the Little Ice Age, and no specimens from any later than the 1976 Heat Wave had thus far been recovered. The disappearance of the Snorkacks, it was said, had been an early warning sign of the global climate change which had troubled the entire world, wizarding and muggle, for the better part of the last half-century. A cooperative partnership had been reached between the WAS and the Royal Society a scant decade after the WAS’s founding , allowing research witches and wizards to pool their resources with muggle scientists, in time to prevent a catastrophe that the wizarding world would otherwise have been unlikely to survive.
In her speech at that evening’s gala, Luna told the story of how it all happened, to reveal the person who had singlehandledly started this series of events, which resulted in not only a golden age of discovery in the field of cryptozoology, but also an era of peace and cooperation between both worlds, allowing restrictions imposed by the Statute of Secrecy to be loosened for the first time in nearly five hundred years, all in the pursuit of knowledge for its own sake.
Hermione Granger, who had been grumbling in her chair the entire time, rose when acknowledged. Luna Lovegood beamed at her aging friend, the witch who had gone from being her most skeptical critic to her most dedicated – and most challenging – supporter in a mere half-century.
