Be sure to watch the video. The exhibit is a cast of a skeleton from Patagonia. And the species hasn't even been named yet.
That's not a crocodile, THIS is a crocodile...
To file away under 'really big extinct things', they've just published findings on a 10 meter long cretaceous crocodile. Interestingly, the article also involves a bit of speculation about the nature of the extinction event separating the Jurassic and the Cretaceous...
Here's a nice article in the Washington Post
And here's the paper...
Fresh out of Alberta: New Research on Dinosaur Babies
Back in 2010, the remarkably complete remains of a juvenile Chasmosaurus was found in Dinosaur Park in Alberta, and a paper has just come out describing it, complete with a new reconstruction made by the authors and Michael Skrepnick (the paleoartist who lent us his wonderful Diplodocus for our cover art!).
What makes the find exciting is the amount of detail we can now have about a ceratopsid while it grows. There's been a recent trend in dinosaur paleobiology to emphasize the amount of anatomical (and thus perhaps physiological, behavioral and ecological) changes that happen during the animal's life - and so getting a good look at dinosaurs during growth is imperative. Also, baby dinosaurs!
See here for the news item (and reconstruction!)
Here's the journal article

Dirty dancing
A research team led by Martin Lockley and Karen Houck of the University of Colorado Denver have found new evidence for courtship behavior in theropod dinosaurs. According to Lockley et al, "scraping" traces associated with theropod footprints are morphologically similar to those left by modern ground-nesting birds in leks. If the behavior was indeed similar, then we can add courtship displays to the ever-growing list of similarities between avian and non-avian dinosaurs.

Patient(s) Zero of the K-Pg Event?
A paleontologist in New Jersey is looking close to home for evidence of the K-Pg event. Kenneth Lacovara of Rowan University hopes to find an assemblage that can be directly associated with the proximate cause of the non-avian dinosaurs' extinction. More at the New York Times.
A beautiful beetle preserved in amber, 99 million years old
Very nice images are available here, at The Artful Amoeba, a Scientific American blog.
A very large duckbilled dinosaur with a very small cranial crest
Scientists are calling it the "superduck."
But the really interesting thing is the suggestion that heterochrony (or changes in developmental timing) might explain the evolution of duckbill cranial crests.
