If you have access to the online version of Science (via a university or
research library, for example), the paper in question is at this site:
and the abstract (which I think everyone has access to?) is at
and the news report at:
I do concur with the point already made by several people: although the
heart (if that's what this concretion is) morphology is CONSISTENT with a
high level of activity, this does not necessarily imply full avian-style
What I would now like to see is a preserved heart of sphenosuchians and
other non-crocodilian members of the Pseudosuchia, to find out if the unique
modern croc condition represents a basal archosaur form, or (as I suspect,
for scenario-based rather than hard evidence-based reasons) is a derived
feature within the croc lineage alone.
