Molecular evidence for the hadrosaur B. canadensis as an outgroup to a clade containing the dinosaur T. rex and birds [PDF]

, 2009
Molecular analysis of collagen sequences from an 80 million year old hadrosaur _B. canadensis_ and a 68 million year old dinosaur _T. rex_ suggest strongly that _B. canadensis_ is an outgroup to a clade containing _T.

Elliptic Fourier analysis as a tool for the taxonomic identification of isolated theropod pedal phalanges

The Anatomical Record, EarlyView.
Abstract Studies of Upper Cretaceous deposits in North America have provided invaluable insights into the continental ecosystems of this time. Theropod (Saurischia, Dinosauria) pedal phalanges are commonplace in these deposits but can be difficult to identify at a finer taxonomic resolution.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Forelimb reduction and digit loss were evolutionarily decoupled in oviraptorosaurian theropod dinosaurs

Royal Society Open Science
Theropod forelimbs exhibit wide morphological disparity, from the elongated wings of birds to the diminutive arms of T. rex. A wealth of work has sought to understand the evolution of bird flight via arm elongation, but despite widespread occurrences of ...

The postcranial skeleton of Monolophosaurus jiangi (Dinosauria: Theropoda) from the Middle Jurassic of Xinjiang, China, and a review of Middle Jurassic Chinese theropods [PDF]

, 2010
The Middle Jurassic was a critical time in the evolution of theropod dinosaurs, highlighted by the origination and radiation of the large-bodied and morphologically diverse Tetanurae.

Development of a framework for implementing digital serious games in anatomy education: A single‐centre qualitative study

Anatomical Sciences Education, EarlyView.
Abstract Serious games are emerging as innovative tools in medical education, yet their adoption in anatomy teaching remains limited due to educator hesitancy, institutional constraints, and design challenges. This qualitative study explores the perspectives of anatomy educators on digital serious games and proposes a framework for their implementation.

Opposing consensus science through scholarly practices: The role of claims maintenance

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...

Vocabulary of Autistic Preschool Children With Limited Language: Alignment With Early Word Inventories

Autism Research, EarlyView.
ABSTRACT There is a critical need to understand the early vocabulary of young children with autism who have limited language, defined in this study as producing fewer than 20 different spontaneous and functional spoken or augmented words, to better inform educational targets and vocabulary selection for spoken as well as augmentative and alternative ...

String Figuring young children's perspectives of quality in English early childhood education and care

British Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.
