Long-term cycles in the history of life: Periodic biodiversity in the Paleobiology Database [PDF]
PLoS ONE 3(12): e4044. (2008), 2008 Time series analysis of fossil biodiversity of marine invertebrates in the Paleobiology Database (PBDB) shows a significant periodicity at approximately 63 My, in agreement with previous analyses based on the Sepkoski database. I discuss how this result did not appear in a previous analysis of the PBDB.

A Problem in Paleobiology [PDF]
arXiv, 2002 We present a stochastic model for the size of a taxon in paleobiology, in which we allow for the evolution of new taxon members, and both individual and catastrophic extinction events. The model uses ideas from the theory of birth and death processes.

Paleobiology: A Tooth for a Tooth [PDF]
Current Biology, 2017 Many vertebrates replace teeth through shedding of the functional tooth. New analyses of a fossil fish demonstrate that shedding involved tooth resorption, a primitive feature in bony fishes, but absent in sharks and their relatives.

Developmental paleobiology of the vertebrate skeleton [PDF]
Journal of Paleontology, 2014 Studies of the development of organisms can reveal crucial information on homology of structures. Developmental data are not peculiar to living organisms, and they are routinely preserved in the mineralized tissues that comprise the vertebrate skeleton, allowing us to obtain direct insight into the developmental evolution of this most formative of ...

Core Competencies for Training Conservation Paleobiology Students in a Wicked World
Frontiers in Ecology and Evolution, 2022 Despite the promise conservation paleobiology holds for using geohistorical data and insights to solve conservation problems, training in the field typically does not equip students to be competent environmental problem solvers.

A guide for microscopic description of fossil stromatolites [PDF]
Brazilian Journal of Geology, 2023 Stromatolites are laminated biosedimentary structures of great importance for paleobiological, paleoecological, and paleoenvironmental analyses, mainly in Precambrian rocks. Their value is related to the glimpse of past life recorded in their lamination,

What is conservation paleobiology? Tracking 20 years of research and development
Frontiers in Ecology and Evolution, 2022 Conservation paleobiology has coalesced over the last two decades since its formal coining, united by the goal of applying geohistorical records to inform the conservation, management, and restoration of biodiversity and ecosystem services.

Shell variability in the stem turtles Proterochersis spp. [PDF]
PeerJ, 2018 Background Turtle shells tend to exhibit frequent and substantial variability, both in bone and scute layout. Aside from secondary changes, caused by diseases, parasites, and trauma, this variability appears to be inherent and result from stochastic or ...
