Don't dinosaurs have WZ and ZZ, like birds?
- gweinberg 6y agoLikely they did, but I don't think we have the DNA to know for sure. Even if we did have some trapped in amber inside insects like in Jurassic Park, we couldn't link to bones. On Land of the Lost "Grumpy" was called he and "Alice" was called she, but I don't think anyone knew their sex for sure. "Alice" was an Allosaurus.
