Congratulations Stilwell & team, you just hit the
"We do have some ideas..."
Hehe, yeah, I guess so. :D
I had been very much hoping for something like that,
after I read:
Stillwell et al. (2006):
Dinosaur sanctuary on the Chatham Islands, Southwest
Pacific: First record of theropods from the K–T
boundary Takatika Grit.
Cretaceous–Tertiary (K–T) boundary (ca. 65
Ma) sections on a Southwest Pacific island containing
dinosaurs were unknown until March 2003 when theropod
bones were recovered from the Takatika Grit on the
remote Chatham Islands (latitude 44° S, longitude 176°
W), along the Chatham Rise. Tectonic and
palaeontologic evidence support the eastward extension
of a ca. 900 km land bridge that connected the islands
to what is now New Zealand prior to the K–T
boundary. The Chathams terrestrial fauna inhabited
coastal, temperate environments along a low-lying,
narrow, crustal extension of the New Zealand
subcontinent, characterised by a tectonically dynamic,
volcanic landscape with eroding hills (horsts)
adjacent to flood plains and deltas, all sediments
accumulating in grabens. This finger-like tract was
blanketed with a conifer and clubmoss (Lycopodiopsida)
dominated forest. The Chatham Islands region would
have, along with New Zealand, provided a dinosaur
island sanctuary after separating from the Gondwana
margin ca. 80 Ma.
