Ornithotarnocia is a Mesozoic bird ichnogenus. It is similar to the ichnogenus Aquatilavipes, but has a thicker digit III impression and is more asymmetrical. [1]
Paleontology, palaeontology or palæontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised faeces (coprolites), palynomorphs and chemical residues. Because mankind has encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred in the year 1978.

Caririchnium is an ichnogenus of ornithopod dinosaur footprint, belonging to either derived iguanodonts or basal hadrosauroids. It includes the species Caririchnium lotus from Lower Cretaceous Jiaguan Formation and C. protohadrosaurichnos from Upper Cretaceous Woodbine Formation. Specimens are also known from the Lower Cretaceous El Castellar Formation and Camarillas Formations.
Gregaripus is an ichnogenus of dinosaur footprint. It is possibly synonymous with Anomoepus, and may represent underprints that are instead referable to this ichnogenus.
Saurexallopus is an ichnogenus of four-toed theropod footprints from the Late Cretaceous period. The type ichnospecies is S. lovei, named and described in 1996 from the Harebell Formation. The taxon was originally named Exallopus, but later renamed as Saurexallopus as the former was preoccupied by a polychaete. A second species, S.zerbsti, was named and described in 2004 from the Lance Formation. In 2012 a four-toed track from the Cantwell Formation was referred to Saurexallopus indet. It was also suggested that Saurexallopus was produced by a therizinosaur taxon. In 2013 based on skeletal proportions it was suggested that the ichnotaxon was instead produced by an oviraptorosaur taxon. In 2014 a third species was named, S.cordata, from the Wapiti Formation. In 2018 several tracks from the Blackhawk Formation were referred to Saurexallopus indet.
Avipeda is a Mesozoic to Cenozoic bird track ichnogenus. The morphogenus is defined by having three forward facing toes without inter-digit webbing. Additionally the angles between the forward toes does not exceed 95°, while the digits are all of similar length. Avipeda is similar to the ichnogenus Aquatilavipes, but has shorter and thicker toe prints.
Ludicharadripodiscus is a Mesozoic bird ichnogenus. It is similar to the ichnogenus Aquatilavipes, but more frequently preserves impressions of the hallux.
Aviadactyla is a Mesozoic bird ichnogenus. It is similar to the ichnogenus Aquatilavipes, but in this ichnogenus the toeprints fuse farther from the body and have a "stick-like" character.
Archaeornithipus was a genus of large bird ichnogenus discovered in Spain. The tracks date back to the Berriasian stage of the Cretaceous, making them among the oldest bird trace fossils in the world.
Ignotornis was a bird ichnogenus dating back to the Barremian-Cenomanian of Colorado, Canada and South Korea.
Jindongornipes was a Cretaceous bird ichnogenus. Similar fossil footprints have been discovered in the Dunvegan Formation of British Columbia. These were among the first known Cretaceous fossil bird tracks in western Canada.
Hadrosaurichnoides is an Early Cretaceous ichnogenus of dinosaur footprint erected by María Lourdes Casanovas Cladellas. The original description attributed the ichnogenus to an ornithopod trackmaker, but in 2001 Lockley and Wright argued that they were actually left by theropods because the prints were longer and narrower than would be expected for ornithopod tracks.
This timeline of ankylosaur research is a chronological listing of events in the history of paleontology focused on the ankylosaurs, quadrupedal herbivorous dinosaurs who were protected by a covering bony plates and spikes and sometimes by a clubbed tail. Although formally trained scientists did not begin documenting ankylosaur fossils until the early 19th century, Native Americans had a long history of contact with these remains, which were generally interpreted through a mythological lens. The Delaware people have stories about smoking the bones of ancient monsters in a magic ritual to have wishes granted and ankylosaur fossils are among the local fossils that may have been used like this. The Native Americans of the modern southwestern United States tell stories about an armored monster named Yeitso that may have been influenced by local ankylosaur fossils. Likewise, ankylosaur remains are among the dinosaur bones found along the Red Deer River of Alberta, Canada where the Piegan people believe that the Grandfather of the Buffalo once lived.
The 20th century in ichnology refers to advances made between the years 1900 and 1999 in the scientific study of trace fossils, the preserved record of the behavior and physiological processes of ancient life forms, especially fossil footprints. Significant fossil trackway discoveries began almost immediately after the start of the 20th century with the 1900 discovery at Ipolytarnoc, Hungary of a wide variety of bird and mammal footprints left behind during the early Miocene. Not long after, fossil Iguanodon footprints were discovered in Sussex, England, a discovery that probably served as the inspiration for Sir Arthur Conan Doyle's The Lost World.
