120 million year old fossil Brazilian spider. Check out the detail on this preservation.
A spider that lived at the time of the dinosaurs. This ~120 million year-old fossil spider in limestone has been replaced by the mineral goethite (iron oxide-hydroxide). Spiders go back more than 250 million years and their diversity does not appear to have been affected by the great extinction event that wiped out the dinosaurs and other critters. Today, spiders are the most abundant predators on land. Perhaps during the time of dinosaurs as well?

natgeo Video by @Filipe_DeAndrade@brianmoghari and @mckenziebarney | When it comes to finding a partner, jumping spiders can rival any online dating stories you may have heard. Their courtship rituals are filled with deception, cannibalism and dancing. And in this micro-universe, the ladies call the shots. If the male can win her over, they’ll mate. And if not, she’ll eat him. That’s why we jumped on the opportunity to be able to film this unique courtship behavior. It’s not everyday that someone puts their life on the line just to get some action. Their lives are complex and the opportunity to film them allowed us to try a new technical approach. I left this experience with a newfound appreciation for spiders. Check out the entire sequence in my series #WildUntamed on natgeowild.com/untamed or click the link in my personal bio.
To those who follow me and surprisingly look through my blog (I still believe about 90% of y'all are porn bots, to those who aren’t “hi!”), I apologize for the constant stream of ‘humans are weird’, 'earth is space Australia’, and various other tagged reblogs! I am loving these tags so much!
I should really start tagging my reblog, that’s a thing I should do over my two days off.
