Yes, I do participate in the All Yesterdays movement. I'm just slow.
I also submitted entries for the Irregular Books contest, though I couldn't find the time to invest in them as much as I would have wanted.
This one depicts a small dromaeosaur that impales his prey on plant thorns. Unlike the food caches of modern shrikes, though, these collections of dead animals are used as a courtship display. Somewhat like modern bowerbirds, these dinosaurs decorate their branch territory with a collection of carcasses of different animals and stick around to show their collection to passing females. It is a honest signal of hunting skills, as the less successful males have to eat their own displays.
This young male has been fortunate enough to find a good, open display branch and been able to defend it from other males. He's not a particularly good hunter, however, and is unlikely to impress a female with such a pitiful collection. He's rather scrawny himself, too, which doesn't help.
