Ambodonta

Ambodonta is a genus of extinct marine bivalve mollusks that lived during the Carboniferous period. These fossils are typically found in the fossil record of North America and Europe, indicating a wide distribution across the ancient seas of the time. Ambodonta shells are characterized by their generally small to medium size and a distinct, often asymmetrical, shape. The shell surface may exhibit radial or concentric ornamentation, though specific features can vary between species.

The ecological role of Ambodonta is understood through their fossilized remains. They were likely infaunal or epifaunal organisms, meaning they lived either burrowed within the seafloor sediment or on the surface of it. Their presence suggests a marine environment with a substrate suitable for their lifestyle, possibly shallow, soft-bottomed areas. As bivalves, they were filter feeders, drawing water in to extract microscopic food particles. Their extinction, like that of many other Carboniferous marine invertebrates, is attributed to environmental changes occurring at the end of the period. Studying Ambodonta provides insights into the biodiversity and paleoecology of ancient marine ecosystems.
