Hey paleo friends, looking for paper recs (for my macroevolution senior seminar)! Topic is currently labeled as “deep time, fossils, taphonomy”. I’d ideally like a research paper that will expose my students to some “typical” paleobio research, but include discussion of biases in the fossil record.
