The Carboniferous (/ ˌ k ɑːr b ə ˈ n ɪ f ər ə s / KAR-bə-NIF-ər-əs) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period 358.9 Ma (million years ago) to the beginning of the Permian Period, 298.9 Ma. In North America, the Carboniferous is often treated as two separate geological periods, the

· Newly discovered tree fossils from ∼350 Ma in New Brunswick, Canada, are architecturally unique, and Gastaldo et al. interpret them to presage modern tree-fern lineage growth forms. These fossils, preserved by earthquake-induced burial in an Early Carboniferous rift lake, may represent early evidence of a subcanopy forest niche.

The Lower Carboniferous limestone sequence of southwest Britain shows a four-stage development. Firstly, after the initial Carboniferous eustatic sea-level rise a siliciclastic marine system developed, representing the 'start-up' phase of carbonate deposition. During Hastarian-Arundian times.
