In the 1800's, some fossil teeth belonging to ceratopsians and hadrosaurs were discovered. They were classified under the genus Trachodon. When it was realized that the teeth did not come from one type of animal, the genus Trachodon became dubious.

These creatures are far apart in time. Trachodon is from the Late Cretaceous and the Wooly Mammoth are from Pleistocene period.
i think that the trachodon defended itself by its stiff tail
Trachodon and woolly mammoths lived in different time periods. Trachodon, a type of dinosaur, lived during the Late Cretaceous period around 70 million years ago, while woolly mammoths lived during the Pleistocene epoch around 2 million years ago. Their existence did not overlap, so their fossils would not be found together.
Tyrannosaurus is a carnivore. Stegosaurus is considered an armored dinosaur, although its plates were probably minimally effective as armor. Trachodon was a hadrosaur, or duck billed dinosaur. Thus, the incorrect pairing is horned dinosaur and Diplodocus. Diplodocus didn't have any horns.
Diplodocus did not have a horn. Diplodocus was a sauropod walking on all four limbs with an extremely long neck and tail.

"Duckbill" is a vernacular term for Hadrosauridae, a large family of herbivorous dinosaurs, with many different species. Hadrosauroids Bactrosaurus Cedrorestes Eolambia Gilmoreosaurus Levnesovia Protohadros Tanius Hadrosaurids (valid genera) Amurosaurus Anasazisaurus Anatotitan Angulomastacator Aralosaurus Arenysaurus Barsboldia Brachylophosaurus Charonosaurus Claosaurus Corythosaurus Edmonotosaurus Gryposaurus Hypacrosaurus Hypsibema Jaxartosaurus Kerberosaurus Koutalisaurus Lambeosaurus Lophorhothon Maiasaura Naashoibitosaurus Nanningosaurus Nipponosaurus Olorotitan Pararhabdodon Parasaurolophus Prosaurolophus Sahaliyania Saurolophus Secernosaurus Shantungosaurus Telmatosaurus Tethyshadros Tsintaosaurus Velafrons Wulagasaurus Zhuchengosaurus Hadrosaurids (dubious genera) Arstanosaurus Cionodon Diclonius Hadrosaurus Hypsibema Mandschurosaurus Microhadrosaurus Orthomerus Thespesius Trachodon
No. Dinosaurs never swam and never flew. Some would enter shallow water to catch prey and possibly bathe, but were not adapted for life in the water. Don't get confused with animals like Plesiosaurs or Mosasuars, both of which are reptiles NOT dinosaurs. These reptiles did live at the same time as dinosaurs (throughout the Cretaceous). Remember: All dinosaurs were reptiles, but not all reptiles were dinosaurs. There were marine reptiles and flying reptiles that lived at the same time as dinosaurs. ----------------------------------------------------------------------That's not exactly right. If the questioner means were there any aquatic dinosaurs, then the answer is correct. However, he's asking if any dinosaurs swam, I think some of the hadrosaurs did - maybe to the extent that modern muskrats do. There's pretty good fossil evidence that indicates some of these animals (Trachodon for e.g.) had webbed feet, which would suggest they weren't afraid to get their feet wet. As noted above, the only truly aquatic reptiles that lived during the age of dinosaurs were plesiosaurs, ichthyosaurs, and mosasaurs. The mosasaurs were just huge Varanid lizards, as the above answer notes. I'm not sure how the plesiosaurs or ichthyosaurs are currently classified, but they're definitely not dinosaurs.
