What kind of dinosaurs made tracks?
The match between fossil track and fossil skeleton is rarely 100%. Vertebrate paleontologists respect this uncertainty by classifying tracks as ichnotaxa Grallator , for example (for three-toed, bipedal tracks), or Brontopodus (large quadrupedal tracks). The scientists then speculate about exactly which fossil skeletal remains might be from which animals making the tracks. Then, using skeletal fossils to go by, they consider what animals are known to have been alive at the time the tracks were made and in the same general area as the trackway. Sometimes the best match is to a large group of dinosaurs. Remember that skeletal remains and trackways are incomplete records of the past because preservation requires a lucky coincidence of events. Many species most likely lived and became extinct without a trace. Also, most skeletal remains are incomplete; small foot bones may not have been preserved with the rest of the skeleton. But if a match can be proposed, it provides additional informat
