Fossil evidence reveals vertebrate predation on Mississippian blastoid Pentremites spicatus
Summary
This scientific paper presents evidence of vertebrate predation on the Mississippian blastoid Pentremites spicatus, a type of extinct echinoderm. The study analyzes trace fossils showing predation and recovery patterns, describing how these blastoids were preyed upon by vertebrates (likely fish) during the Mississippian period. The research provides insights into ancient trophic interactions and predator-prey dynamics in the fossil record, using partially healed injuries and modified prey remains to identify both predator and prey taxa.

· 3 pulledPredation acts as a major evolutionary selective pressure, but this process must often be approached indirectly in the fossil record.
Predation and consumption are often destructive processes for the targeted prey, and trace fossils preserving examples of these trophic interactions often are found on modified, discarded, unconsumed portions of prey or partially healed injuries on survivors of failed predation attempts.
Positive identification of both predator and prey taxa can be challenging in these cases, but when possible, these rare traces can provide insights into the palaeobiology
