“The Last Guard” Probably one of the most fascinating fossils found and in my opinion one of the saddest: Several fossils of psytacosaur cubs found by paleontologist Dean Lomax under the protection of what appears to be an older brother who temporarily cared for them before being killed by a stream of volcanic debris. In Dean’$ own words: “The largest fossil does not have the dimensions of a sexually mature adult, so it could not be the father and was probably an older brother of the little cubs The discovery is exceptionally well-preserved and appears in his book: Locked in Time Animal Behavior Unearthed in 50 Extraordinary Fossils, art: Bob Nicholls 3h12
