Australian Ordovician, Silurian, and Devonian Bryozoa Fossil Records

Australian fossil records of bryozoa from the Ordovician, Silurian, and Devonian periods, compiled by the Australian Ocean Data Network. The dataset is based on a study investigating skeletal structures and species distribution, with data last updated in June 2026. It describes bryozoan faunas from specific horizons in central-western New South Wales and the Fitzroy Basin.

Use Cases

• Analyzing bryozoan skeletal structure development based on the study's original aim
• Mapping species distribution across different stratigraphic successions as described
• Studying faunal abundance in specific geological horizons like the Fitzroy Basin
• Investigating isolated fossil occurrences where only a few species were collected

Strengths

• Focuses on three specific geological periods: Ordovician, Silurian, and Devonian
• Includes data from identified regions like central-western New South Wales and the Fitzroy Basin
• Data sourced from field parties of the Bureau of Mineral Resources
• Last updated date is explicitly provided: 2026-06-23

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic bias inherent to the specific Australian study areas
