Most often there are limited fossils to describe some animals and plants, but now they have enough fossils to define a whole ecosystem in the late Cretaceous.

Until relatively recently paleontologists have concentrated largely on the fossils at a site and pretty much ignored the sedimentary rock they were found in. This has changed and as a result we are learning a great deal more about the environment and ecosystems that the organisms inhabited.
Still I gotta wonder how much data could we have acquired if this was something we had been doing for numerous decades and not just the past two to two and a half.
I'm always still in trouble again

Interesting times the volume of discoveries and research results has never been this high in a very long time. Even the research in older fossils is increasing.Glendower: I can call spirits from the vasty deep.

One that springs immediately to mind were the discovery of transitional "flatfish" dating from the Eocene at the Paris National Museum of Natural History and Britain’s Natural History Museum in London by Brian Friedman. Until then even the majority of scientists conceded that their asymmetrical, one-sided eye arrangement was a characteristic that arose suddenly in flatfish because they could not comprehend any benefit for the fish if it took millions of years for an eye to migrate from one side to the other. Many assumed that the flatfish’s anatomy was probably a result of a few chance mutations, a through a process called "saltation."
