Comment on Archaeopteryx - Landing by EWilloughby
Jurassic Solnhofen was an archipelago in a warm, shallow, very salty sea with isolated lagoons formed by coral and sponge. The environment would have been tropical, with a lot of smallish plants (no trees) and tons of small animals. It's thought that sometimes the lagoons were dry and muddy, but I don't think it would be categorized as arid.
From what I read in Gregory S Paul's "Predatory Dinosaurs of the World" conifer scrub. What source did you use for the ecology? My source is, granted, more than 20 years old.
Mostly Taking Wing by Pat Shipman.
Hmm, sounds like your reference is the most recent.
