Bajocian (middle Jurassic) Ammonitina of New Zealand [PDF]
New Zealand Journal of Geology and Geophysics, 2000 Abstract A relatively rich, previously unknown fauna of Ammonitina is described from the Bajocian of southwest Auckland. The great majority are Sphaeroceratidae. The Chondroceras fauna has yielded C. orbignyanum and C. (Defonticeras) cf. oblatum, clearly indicating the Humphriesianum Chron.

Tracking dinosaurs in Scotland [PDF]
, 2005 <p>Dinosaurs, the Loch Ness Monster not included, are a rarity in Scotland. Although dinosaurs have been known of in England and elsewhere in the world for over 300 years, it was only in the last 23 years that dinosaurs began to appear in Scotland.

The Anatomical Record, EarlyView.Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Accretionary Tectonics of the North American Cordillera [PDF]
, 1983 Continental geology stands on the threshold of a change that is likely to be as fundamental as plate-tectonic theory was for marine geology. Ongoing seismic-reflection investigations into the deep crustal structure of North America are verifying that ...

The Anatomical Record, EarlyView.Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

The Anatomical Record, EarlyView.Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.
