The effect of intervertebral cartilage on neutral posture and range of motion in the necks of sauropod dinosaurs [PDF]

open access: yes, 2013
The necks of sauropod dinosaurs were a key factor in their evolution. The habitual posture and range of motion of these necks has been controversial, and computer-aided studies have argued for an obligatory sub-horizontal pose.

Caudal pneumaticity and pneumatic hiatuses in the sauropod dinosaurs Giraffatitan and Apatosaurus [PDF]

open access: yes, 2013
Skeletal pneumaticity is found in the presacral vertebrae of most sauropod dinosaurs, but pneumaticity is much less common in the vertebrae of the tail.

Review of the Dinosaur Remains from the Middle Jurassic of Scotland, UK

open access: yesGeosciences, 2018
Dinosaurs are rare from the Middle Jurassic worldwide. The Isle of Skye, is the only place in Scotland thus far to have produced dinosaur remains. These remains consist mainly of footprints, but also several bones and teeth.

Inter-vertebral flexibility of the ostrich neck: implications for estimating sauropod neck flexibility. [PDF]

open access: yesPLoS ONE, 2013
The flexibility and posture of the neck in sauropod dinosaurs has long been contentious. Improved constraints on sauropod neck function will have major implications for what we know of their foraging strategies, ecology and overall biology.

The neck of Barosaurus was not only longer but also wider than those of Diplodocus and other diplodocines [PDF]

open access: yes, 2016
Barosaurus is a diplodocid sauropod from the Upper Jurassic Morrison Formation of the western United States, and is known for its very long neck. It is related to the sympatric Diplodocus, and often thought of as more or less identical except with a ...

Crocodile tail traces and dinosaur footprints. Bathonian?- Callovian. Imilchil. High Central Atlas. Morocco

open access: yesGeogaceta, 2021
Three types of ichnites from a new site discovered in Imilchil were studied and described. The structures of pes and manus prints and tail traces of tetrapods provide data to separate: real ichnites (theropod footprints and crocodile tail drag marks ...

Exceptionally simple, rapidly replaced teeth in sauropod dinosaurs demonstrate a novel evolutionary strategy for herbivory in Late Jurassic ecosystems

open access: yesBMC Ecology and Evolution, 2021
Background Dinosaurs dominated terrestrial environments for over 100 million years due in part to innovative feeding strategies. Although a range of dental adaptations was present in Late Jurassic dinosaurs, it is unclear whether dinosaur ecosystems ...

Dinosaur footprints and other Ichnofauna from the Cretaceous Kem Kem Beds of Morocco [PDF]

open access: yes, 2014
We describe an extensive ichnofossil assemblage from the likely Cenomanian-age 'lower' and 'upper' units of the 'Kem Kem beds' in southeastern Morocco.

Life history of Tendaguru sauropods as inferred from long bone histology [PDF]

open access: yesFossil Record, 1999
Sauropod dinosaurs present exceptional challenges in understanding their biology because of their exceptional body size. One of these, life history, can be inferred from the histology of their bones.

The rarity of gastroliths in sauropod dinosaurs – a case study in the Late Jurassic Morrison Formation, western USA [PDF]

open access: yesFossil Record, 2014
Occurrences of suspected sauropod geo-gastroliths and "exoliths" (exotic clasts) are compared with authentic finds of stomach stones in the sauropods Diplodocus, Cedarosaurus, and Camarasaurus.
