addedNew Content:New Exhibit: The Louisville Limestone! Hailing from the state of Kentucky, fossils in this exhibit include a variety of coral species: Arachnopyllum , Cystihalysites , Favosites , Heliolites , Omphyma , Plasmopora , Schlotheimophyllum , Strombodes , and Tryplasma . This is also the oldest exhibit of the batch (425-430 million years old) and represents our first exhibit opened in the Silurian Period!

addedNew Content:New Exhibit: The Westerville Formation! Another marine unit, this exhibit showcases three fossils of Linoproductus , a shelled animal that can also be found in the Naco Formation. These fossils are 305 million years old.

addedNew Content:New Exhibit: The Dunedoo Formation! A new Permian-aged exhibit, and the first to showcase fossils from Australia, this gallery showcases leaves of the famous plant Glossopteris browniana , a species that was widespread just before the onset of Earth's most lethal mass extinction event yet, 252 million years ago.

addedNew Content:New Exhibit: The Fort Crittenden Formation! The oldest of the three new Cretaceous exhibits, this gallery showcases a fossil from the horned dinosaur Crittendenceratops , as well as two tyrannosaurid teeth of an undetermined species. At 75.5 million years old, these dinosaurs are some of my favorite fellow southern Arizonans!

addedNew Content:New Exhibit: The Fruitland Formation! This gallery showcases animal and plant fossils from New Mexico that date back to 75 million years ago. In addition to new fossils of the enormous reptile Deinosuchus, visitors to this exhibit can also view three new in-situ petrified trees that I scanned in the field this past summer.

Continuing to fill in the terrestrial units of the San Juan Basin, New Mexico, this exhibit showcases 73 million-year-old fossils from three dinosaur species: the carnivore Bistahieversor, the herbivore Naashoibitosaurus, and the armored Ziapelta .

Bug fixes:

Within the inspection page, the prompt to hear a pronunciation will not not appear if there is not one available.

Final Thoughts:

I'm thrilled to be able to share the final batch of new exhibits for 2025! It has now been nearly a year since we launched into Early Access for the Windows Beta, and I hope players agree that we've come a long way. With this addition of 7 galleries, that makes for 15 new exhibits total for this year. There are plenty more on the way, that just weren't ready to release this time around; 2026 is going to be full of new and exciting fossils! -Benjamin
