Pennsylvanian
marine/nearshore deposits
Like the Permian, the older Pennsylvanian period was an age
ruled by primitive creatures, giant insects, and alien flora.
Club mosses grew to the size of trees, dragonflies had bodies
the size of baseball bats, and reptiles were getting their
first foothold on the planet. Pennsylvanian research areas
include localities rich in marine organisms such as brachiopods,
bryozoans, trilobites, and crinoids, as well as remains of
terrestrial life such as insects, plants, and vertebrates.
Research of the Pennsylvanian material will shed light on
climatic conditions 300 million years ago and explore the
interactions between different organisms of the time. Some
research topics are as follows:
Pennsylvanian
plant assemblages
Brachiopods,
bryozoans, crinoids, trilobites, and invertebrates of the
inland sea
Vertebrate
remains from nearshore estuaries
Vertebrate
trackways created by reptilian ancestors to mammals
Invertebrate
burrows in the marine setting
