City of Rocks State Park is a geologic treasure; with towering, sculptured rock pinnacles and boulders rising as high as 40 ft separated by paths or lanes resembling city streets. The boulders were deposited by a volcanic eruption about 34.9 million years ago. Erosion sculpted the columns and peculiar rock formations over several million years.#NewMexico #geology #hiking #daytrip

Australia's reputation for deadly #wildlife stems from its geological #history, when the continent broke away from Gondwana 100 million years ago, taking some venomous species along for the ride. While 65% of #Australia's snakes are venomous (compared to just 15% worldwide), most evolved from a single ancestor that arrived 40 million years ago, diversifying into different habitats and developing more potent venoms over time.https://www.discoverwildlife.com/animal-facts/why-does-australia-have-so-many-deadly-animals #evolution #snakes #jellyfish #platypus #octopus #geology #animals
