Trilobite research
- Trilobite fossil material from the Tiout section in Morocco, representing the first occurrence of trilobites in West Gondwana and some of the oldest trilobite fossils in general, is determined to be approximately 519.62-million-years-old by Sinnesael, Millard & Smith (2024).[6]
- Hopkins, Gutiérrez-Marco & Di Silvestro (2024) describe fossil material of Leptoplastides salteri from the Fezouata Formation (Morocco), extending known range of this species from Avalonia into Gondwana.[7]
