Deciphering Temperature Seasonality in Earth's Ancient Oceans

Ivany, Linda C.; Judd, Emily J. (2022)

Ongoing global warming due to anthropogenic climate change has long been recognized, yet uncertainties regarding how seasonal extremes will change in the future persist. Paleoseasonal proxy data from intervals when global ...
Environmental and biological controls on the diversity and ecology of Late Cretaceous through early Paleogene marine ecosystems in the U.S. Gulf Coastal Plain

Sessa, Jocelyn A.; Bralower, Timothy J.; Patzkowsky, Mark E.; Handley, John C.; Ivany, Linda C. (2012)

The late Mesozoic through early Cenozoic is an interval of significant biologic turnover and ecologic reorganization within marine assemblages, but the timing and causes of these changes remain poorly understood. Here, we ...
The fidelity of oxygen and strontium isotope values from shallow shelf settings: Implications for temperature and age reconstructions

Sessa, Jocelyn A.; Ivany, Linda C.; Schlossnagle, Trevor H.; Samson, Scott D.; Schellenberg, Stephen A. (2012)

The oxygen and strontium isotopic ratios of marine carbonates are widely employed to derive paleotemperature and age, respectively. While open ocean samples are the standard source for these measures, shelf settings can ...
Out of the oven and into the fire: Unexpected preservation of the seasonal delta O-18 cycle following heating experiments on shell carbonate

Moon, Lindsay R.; Judd, Emily J.; Thomas, Jay; Ivany, Linda C. (2021)

Oxygen isotope values of shell carbonate sampled along the growth trajectory of fossil mollusks provide one of the few types of proxy data available for reconstructing seasonal temperature variation in Earth's past. ...
Phanerozoic Trends in the Global Diversity of Marine Invertebrates

Alroy, John; Aberhan, Martin; Bottjer, David J.; Foote, Michael; Fursich, Franz T.; Harries, Peter J.; Hendy, Austin J. W.; Holland, Steven M.; Ivany, Linda C.; Kiessling, Wolfgang; Kosnik, Matthew A.; Marshall, Charles R.; McGowan, Alistair J.; Miller, Arnold I.; Olszewski, Thomas D.; Patzkowsky, Mark E.; Peters, Shanan E.; Villier, Loic; Wagner, Peter J.; Bonuso, Nicole; Borkow, Philip S.; Brenneis, Benjamin; Clapham, Matthew E.; Fall, Leigh M.; Ferguson, Chad A.; Hanson, Victoria L.; Krug, Andrew Z.; Layou, Karen M.; Leckey, Erin H.; Nurnberg, Sabine; Powers, Catherine M.; Sessa, Jocelyn A.; Simpson, Carl; Tomasovych, Adam; Visaggi, Christy C. (2008)

It has previously been thought that there was a steep Cretaceous and Cenozoic radiation of marine invertebrates. This pattern can be replicated with a new data set of fossil occurrences representing 3.5 million specimens, ...
Variation in delta N-15 from shell-associated organic matter in bivalves: Implications for studies of modern and fossil ecosystems

Das, Shibajyoti; Judd, Emily J.; Uveges, Benjamin T.; Ivany, Linda C.; Junium, Christopher K. (2021)

Nitrogen stable isotopes (delta N-15) of organic matter can aid in the reconstruction of food webs and, when applied to fossil systems, may help resolve uncertainty about trophic position and provide tests for hypotheses ...
