Organismic and Evolutionary Biology
The University of Texas at Austin
I am an Assistant Professor at UT Austin in the Department of Geosciences. My students and I are involved with many paleontological, geobiological, and sedimentological projects; check out specific projects and facilities on our website: www.jsg.utexas.edu/martindale/
I am primarily interested in marine paleoecology and the geobiology of carbon cycle perturbation events (e.g. mass extinctions, ocean anoxic events, and ocean acidification events in deep time). My research also includes carbonate sedimentology and the paleontology/paleobiology of reef builders (e.g corals and sponges). I am currently working on the Pliensbachian/Toarcian reef crisis and Toarcian Ocean Anoxic Event from the Early Jurassic (~183 Ma). My doctoral research focused on the reef demise and extinction at the Triassic-Jurassic (T-J) boundary, which has been hypothesized to be an ocean acidification event caused by the rapid eruption of the Central Atlantic Magmatic Province and subsequent release of carbon dioxide. Extinction events, such as the Triassic/Jurassic, draw attention for their catastrophism; however, lesser extinction events can be just as interesting, particularly for resolving questions pertaining to species survival and ecosystem recovery. The Late Triassic and Early Jurassic events will help us understand what environmental conditions cause massive ecosystem collapse, and what conditions marine biota can survive. A large part of my research involves the study of Upper Triassic and Lower Jurassic reef ecosystems, the newly evolved scleractinian corals, and reef variations geographically and temporally. Another aspect of my research is Early Jurassic Lagerstatten, which preserves\ both pelagic and benthic communities across the Toarcian Ocean Anoxic Event. In future work, I am interested in combining my research on ancient ocean carbon cycle perturbations and extinctions with research on modern reef decline and stressors that inhibit the secretion of calcareous skeleton.
