Church doodle! Or, more accurately, stake conference doodle. We had a broadcast from Salt Lake! It was awesome! Elder D. Todd Christofferson spoke to us and his words were inspiring and comforting.
And also I drew dinosaurs because they make me happy.
I don't think it's too far-fetched that large theropods would welcome small mammals to clean bugs out of their feathers. Here T. rex is enjoying a little get-together with her favorite groomers (maybe multituberculates?). She brings the food and they bring the company. Being large predators, I think it's entirely possible that tyrannosaurids were intelligent enough to derive enjoyment from beneficial inter-species interactions.
I like prehistoric happy thoughts.
