Phylogenetics is amazing, given surviving members of a clade we can reconstruct the ancestors. Phylogeny techniques can use additional info, eg paleontological record. Eg here's a nice paper discussing Bayesian phylo combined with rexord sampling. https://www.cambridge.org/core/journals/paleobiology/article/from-fossils-to-phylogenies-exploring-the-integration-of-paleontological-data-into-bayesian-phylogenetic-inference/BF7DB160A01BDD5183252BFB89A9699F https://www.cambridge.org/core/journals/paleobiology/article... I'm in an adjacent field so take it with a grain of salt.
