Extract:

Q: It looks as if the T. rex may have nucleated red cells. Is this so?
Judith Chester, Santa Fe, New Mexico.

A: Well, there are small, red structures within the vessels that look
like nucleated red cells. So on the surface, this is a case of "if it
looks like a duck…." But after 70 million years, just because
something looks familiar doesn't mean that that is what it is. The
fossil record can mimic many things, so without doing the chemistry to
show that there are similarities to blood cells at the molecular
level, I do not make any claims that they are cells.

However, we do know that, except for mammals, all living vertebrates
(fish, frogs, birds, and reptiles) have nucleated red blood cells in
circulation. Mammals are unique in having their blood cells "spit out"
the nucleus before they go into circulation (unless there is a
disease). So, because dinosaurs' closest relatives are crocodiles and
birds, it makes sense that their blood cells would have been
nucleated.

Which blows your little story right out of the water.
