Close-up of the traumatic lesion observed in the right squamosal bone of Big John, a fossilized specimen of the dinosaur species Triceratops horridus. This image shows plaque-like deposition of reactive bone (white arrows) and lytic lesions (black arrows) on the surface around the lesion. These suggest that the lesion was surrounded by newly-formed bone and, therefore, had started to heal. This image was originally published as Figure 1c in the following journal article: Ruggero D’Anastasio, Jacopo Cilli, Flavio Bacchia, Federico Fanti, Giacomo Gobbo & Luigi Capasso (2022) Histological and chemical diagnosis of a combat lesion in Triceratops Scientific Reports, 12, 3941 (2022).

Remake of the original picture of the Drzewica Formation. Terrestrial environment of the Pliensbachian-Toarcian boundary of Fennoscandinavia Inland environment of the Bornholm Coast, nearby the German realm of the Ciechocinek Formation. Includes Ciechocinek Formation (Lower Toarcian, Bones) and Drzwica Formation (Latest Pliensbachian, Footprints) Fauna Sorthat Formation environment, fluvial influenced mainland with Cheirolepidaceae and Bennetitales as dominant flora Dinosaurs are based on material found on various locations of Northern Germany, and Footprints of the underliying Drzewica Formation at the Holy Cross Mountains, connected with Bornholm at the time. Dinosaur Species appeared: Megalosauripus isp. Large Footprints (+65 cm) found on the Drzewica Formation. There is a dorsal vertebrae on the German Margin of the Ciechocinek Formation assigend to Megalosauria (Huene, 1966). Gravisauria spp. representing the Grimmen Sauropod reported on 2014, as a taxon related with Tazoudasaurus. Barapasaurus-like footprints are know from the Drzewica Formation. Coelophysoidea spp. based on coeval Anchisauripus tracks from the Holy Cross Mountains. Basal Ornithischan, related to Eocursor, based on a crouching trace (Gerard Dariusz Gierlinski, Martin G. Lockley, Grzegorz Niedźwiedzki:2009). Massospondylidae spp. based on Otozum-like tracks.
The Canadian Fossil Discovery Centre in Morden boasts the largest collection of marine invertebrate fossils in Canada. Visitors to the museum not only get to see this collection, but can join a dig in search for more fossils at a 109-acre escarpment property. Photo credit: Robyn Hanson

Jinchuanloong is a relatively basal sauropod that measured an estimated 10 m in length. Sauropod skulls typically don't preserve well in the fossil record, but Jinchuanloong is known mainly from the skull, and parts of the neck and tail. Like all sauropods, Jinchuanloong was a quadrupedal herbivore that used its long neck to reach the vegetation that it fed on.
