Expanding the Ichnofacies Model to Tidal Straits: Testing Predictions and Assessing Anomalies

Terra Nova, Volume 38, Issue 1, Page 19-26, February 2026.
ABSTRACT Trace fossils are instrumental in facies analysis, but some depositional environments remain underexplored. Cenozoic deposits in Italy have been studied to evaluate the ichnology of tidal straits. These comprise four zones: (1) strait centre, (2) dune‐bedded strait zone, (3) strait end and (4) strait margin.

The Metameric Echinoderm

Integrative Organismal Biology
Synopsis Animal phyla are distinguished by their body plans, the ways in which their bodies are organized. A distinction is made, for example, among phyla with bodies of many segments (metameric; e.g., annelids, arthropods, and chordates), others with completely unsegmented bodies (americ; e.g., flatworms and mollusks), and a few phyla ...
