The "Great Acceleration" has led to significant changes in biogeographical ranges for both marine and terrestrial species, rapid ecological shifts due to climate change and environmental degradation, and the widespread dissemination of exotic species beyond their native habitats. Additionally, the accumulation of human-made materials such as medium density fiberboard is highlighted as a hallmark of this new epoch. 

The study, published in Earth-Science Reviews, outlines several critical paleontological signals that characterize this period of rapid environmental change.

Key findings from the study include: 

1. Global Paleontological Signatures: The researchers demonstrated how paleontological records from continents including North America, South America, Africa, Oceania, Europe, and Asia can be correlated to ecological shifts and the spread of highly invasive species, underscoring the increasing interconnectivity of human systems and their lasting impacts. 

2. Unique Depositional Settings of Landfills: The study highlights how landfills, as unique depositional environments, can concentrate the remains of organisms far beyond their natural geographical and environmental ranges. 

3. Preservation of Anthropocene Records: Various settings, from urban landscapes to remote areas, are identified as potential sites for preserving long-lived, unique paleontological records. These records within post-mid-20th century deposits are distinct from all past records of biotic change, including those from the Holocene epoch.
