Lazarus species reference
The title and author of the paper I've been going on about over my last few
The gradual extinction of dinosaurs: fact or artifact? G.D. Leahy
(in: Fourth Symposium on Mesozoic Terrestrial Ecosystems, Short Papers. P.J.
Currie and E.H. Koster eds.)
Leahy uses the existence of Lazarus species as one part of his argument that
end-Cretaceous dinosaur extinctions were sudden rather than gradual. The
existence of Lazarus species earlier in the late Cretaceous suggests that
other Lazarus species (whose 'return to life" in the latest Cretaceous is
note recorded, or not yet found) would increase the diversity of animals at
the end. I guess it's another approach to "absence of evidence is not
(necessarily) evidence of absence." Has anyone else updated this look at
terminal Cretaceous Lazarus species?
