It is well known and established that insects and other creatures were larger during dinosaur times because there was more oxygen in the atmosphere, amongst other things. Pretty much everything was bigger because it could absorb more oxygen and nutrients from the environment.

Human or proto human sizes have changed but we're taking like 100k years for humans, not 300 million years ago. As far as earth history is concerned, humans haven't been around long at all and haven't seen much change. Obviously we see change, but mother earth time is a different beast.
