Paleontology: The Smallest of the Giants [PDF]
The first three-dimensionally preserved sauropod dinosaur embryo surprises paleontologists. A member of the gigantic titanosaurs, its peculiar morphology shows how much these animals changed during growth and has implications for ecology and skull development that go beyond paleontology.

Morphological diversity of saber‐tooth upper canines and its functional implications
Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...

Abstract The evolution of organisms can be studied through the lens of developmental systems, as the timing of development of morphological features is an important aspect to consider when studying a phenotype. Such data can be challenging to obtain in fossil amniotes owing to the scarcity of their fossil record. However, the numerous remains of Rancho
