I can’t be the only one who reads outside my discipline to get material to help me cover all those evolutionary phenomena I know little about. I know a bit about fish and arthropods, but my understanding of the details of mammalian evolution is a bit thin — yet for some reason, students are more interested in the history of mammals than of spiders. I really appreciate it when I stumble across information that fills in the gaps in my knowledge in presentable ways, and Nature has done just that with a graphically rich article on How the earliest mammals thrived alongside dinosaurs. There is lots of good stuff here, and I particularly like the emphasis on the importance of fossilized infants. Development matters!
Sometimes it goes a little too far, though — for example, this illustration is way too dense to be useful, but it it interesting.
