昨日世界：古生物學家帶你逆行遊獵五億年前的世界，16個滅絕生態系之旅

Halliday's storytelling makes deep time feel alive, but I wonder if this was planned from the start or developed during research.

The book spans hundreds of millions of years, and I’m curious if readers felt the pacing helped or hindered their understanding of such vast timescales.

The selections felt very intentional, but I wonder what influenced those choices—was it based on significance, available evidence, or narrative flow?
