 here too is you'll actually find insect traces where they were underneath the bark burrowing in just like modern ones do. This log, they call the discovery log because this is actually a pretty important discovery. What you're looking at here are insect traces, an actual nest, like little capsules here and you can see they're lined up, little capsules of some nest of some kind of insect that actually lived in this log. Here, so you can see them here and here coming out. Now these have been interpreted to be bees nests and if that's true these will be the earliest bees, the earliest record of bees by about 130 million years. Some entomologists disagree and say that this is very similar to some of the traces that modern beetles make rather than bees but what they did is some of these capsules in here, they went in and they found some preserved resins and they actually tested them for geochemically and they found the chemical that bees secrete. So some more work needs to be done on these to verify these results but they were definitely made by some kind of insect and it's a great example of how insects lived in these yurt logs and used them as a food source and as a home.
