Re: Dinos on microcontinents ( was Re: Theropod "migrations")



Regarding the question of dinosaur fossils found in strata within
a microplate...

The "Oregon hadrosaur" may fall into that category.  It was
collected about 3-4 years ago along the Oregon coast.  If my
memory serves, the basement rocks along that part of the coast
are pre-late Cretaceous in age, and are part of a microplate
that was accreted to Oregon in late Cretaceous.

It is possible that the hadrosaur was deposited in Cretaceous
seds. layed down after the plate had accreted to the continent.

My geologic timing may be off, perhaps someone else knows more.
My only source is a newspaper clipping.
