We are all familiar with the terrestrial or rocky planets in our solar system—Mercury, Venus, Earth, Mars, as well as a number of terrestrial satellites such as our moon or Jupiter’s moon, Io, but far less is known about the icy water worlds that populate our solar system.
As the warming planet continues to cause sea levels to rise, new research suggests rising seas eventually could prove detrimental to human health. John Huntley, an assistant professor of paleobiology in the department of geological sciences at MU, has just published his first paper stemming from research he conducted as a senior visiting fellow of the Institute for Advanced Studies at the University of Bologna, Italy, last summer.
COLUMBIA, Mo. --- The drill holes left in fossil shells by hunters such as snails and slugs show marine predators have grown steadily bigger and more powerful over time but stuck to picking off small prey, rather than using their added heft to pursue larger quarry, new research shows.
Researchers who study evidence of predatory behavior in the fossil record generally look for drill holes, repair scars, bite marks, and other signs of predation in fossilized skeletons. But a team of researchers at the University of Missouri has found fossil “snapshots” of predators caught in the act of feeding on their prey.
