Author and ichnologist Martin takes readers on a spellbinding tour of the myriad types of trace fossils that dinosaurs left behind during their 165-million-year reign.
Martin, an ichnologist at Emory University in Atlanta.
Certainly, some of the vertebrate ichnotaxa he described are indeed dubious as discussed above, but the dismissal of the entire assemblage by Abel (1935) and the subsequent assignment of the ichnotaxa to 'unrecognized or unrecognizable' in the Treatise on Invertebrate Paleontology (Hantzschel 1975) essentially removed Hylopus (?) variabilis from further review by vertebrate ichnologists. Dismissal by previous authors was based in part on the poor quality of preservation of the tracks, and lack of access to the type material.
