H is for heterodontosaurid, Hesperonychus, and Hurdia

It's been a while since I've done the palaeontology news thingy, and there seems to have been a barrage of paleo' the last few days, so:

A tiny new "feathered" ornithischian dinosaur from China, the Early Cretaceous heterodontosaurid Tianyulong confuciusi. My thanks to David Kirkpatrick for sending me a PDF of the Nature article on this wonderful beast.




Life restoration of Tianyulong.



Skeleton of Tianyulong.


Also, we have another tiny, new dinosaur, the smallest carnivorous yet known from North America, Hesperonychus elizabethae, a 19-inch tall theropod from the Late Cretaceous of Alberta, Canada.




An Hesperonychus claw resting upon a quarter.


From the diminutive to the rather large, something for fans of invertebrates, Hurdia victoria, a half-meter long predatory arthropod from the famous Cambrian-aged Burgess Shale of British Columbia. My thanks to mechangel for pointing me towards this one.




Life restoration of Hurdia



Neat stuff, indeed.
