This week on Tiny Matters, we’re talking about dinosaurs: the ancient beasts that died off 65 million years ago but whose remains still captivate us today. Fossils are helping scientists piece together how dinos and other extinct creatures looked and behaved. That info isn’t just inspiring movies like Jurassic Park—it’s helping researchers predict Earth’s future and could even lead to more sustainable tech. Episode transcripts at acs.org/tinymatters
