Happy Halloween from all of us at Wheatland Trees! 🎃🌲🕷️
We are looking back millions of years into Alberta’s original creepy-crawlers for our last Fossil Friday of the 2026 season: prehistoric spiders preserved right inside the ancestors of trees!
Long before Southern Alberta became the beautiful, open landscape of today, it was a dark, humid, subtropical swamp. While dinosaurs get all the credit for being Alberta's ancient monsters, the real Halloween horrors were scurrying around the forest floor—and up the trunks of prehistoric trees.
Here is the spooky connection between Alberta's ancient trees and these eight-legged phantoms: Millions of years ago, Alberta’s ancient conifers bled a sticky, gooey resin - similar to today's conifers. 🌲
For an unsuspecting prehistoric spider, brushing against a tree trunk meant instant entrapment—becoming frozen in time as the resin hardened into amber.🕷
Paleontologists have actually found incredibly rare, pristine spider silk and tiny arachnids trapped in Alberta amber (called Grassy Lake amber after the town in Southern Alberta). The resin sealed out all decay, so these spiders look exactly as they did the day they died.🕸
Just like the spiders spinning webs in spruce and pine today, these ancient arachnids kept the creepy-crawly insect populations in check.
