Uvigerina (foraminifera)

Uvigerina is a genus of small, single-celled marine organisms called foraminifera. They have shell-like structures called tests, made of calcium carbonate, which often exhibit spiral or chambered patterns. Uvigerina live on the ocean floor and play a key role in marine ecosystems by contributing to the sediment and serving as indicators of past environmental conditions. Their fossilized tests are valuable to scientists for studying historical climate changes and the Earth's geological history, as they can survive millions of years and preserve detailed information about ancient oceans.
