The full text was scored for a muricid predator, drill holes in mollusc shells, credit to the radula, and credit to chemical dissolution. An explicit 'rather than the radula' contrast would have refuted the tongue clause. Credit to both, without that contrast, was pre-registered as mixed. Counts were taken only from phrases in the text. https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: 2 limpets drilled by Nucella ostrina in the laboratory trial named in the paper (n = 100). Interpretation: Aristotle's purpurae are muricid gastropods, the purple-dye snails and their relatives. The tongue-like part is the radula. A hole in a shell supports boring only together with an identification of the organ. Chemical assistance from an accessory boring organ, if stated as a joint mechanism, is mixed rather than a pass, because the claim says the tongue bores the hole. https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-pa02-42: mixed, confidence 0.66 https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-pa02-42/result.json https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test https://w3id.org/delphi/ontology/admissibleDatasets A public primary description or experiment on muricid drilling that names the predator and the organ.

Refutes if the text says muricids do not bore shells, or it says the drill holes of the muricid studied are made by dissolution, etching or an accessory boring organ rather than by radular rasping (an explicit contrast such as 'rather than' the radula). Mixed if holes are documented and both the radula and a chemical or accessory boring organ are credited, without an exclusive contrast, or if holes are documented and the boring organ is not identified. Inconclusive, reason data-unavailable, if the file does not contain a muricid drill-hole statement.

An explicit 'rather than the radula' contrast refutes the tongue clause. Counts of drilled specimens are extracted only when the text states them and are reported beside the verdict, which follows the phrase rules. https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test https://w3id.org/delphi/ontology/passCriterion Pre-registered. Supports if the retrieved text both (1) reports holes drilled in mollusc shells by a named muricid or by muricids and (2) credits the radula, or rasping by the radula, with making those holes, and does not say the holes are produced by etching or dissolution rather than by the radula. Confidence 0.70 if the muricid is a Mediterranean purple-dye snail (Hexaplex, Bolinus, Murex or Purpura) and 0.58 if the only muricid named is another genus. https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/aristotle-pa02-42 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/aristotle-pa02-42--claim-test https://w3id.org/delphi/resource/evidence/aristotle-pa02-42--claim-test--dataset-1 http://purl.org/dc/terms/description laboratory muricid drill holes and the organ credited with making them https://w3id.org/delphi/resource/evidence/aristotle-pa02-42--claim-test--dataset-1 http://purl.org/dc/terms/license https://w3id.org/delphi/resource/evidence/aristotle-pa02-42--claim-test--dataset-1 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/EvidenceItem https://w3id.org/delphi/resource/evidence/aristotle-pa02-42--claim-test--dataset-1 http://www.w3.org/2000/01/rdf-schema#label Dataset: Schiffbauer et al. 2008, microstructures of predatory drill holes https://w3id.org/delphi/resource/evidence/aristotle-pa02-42--claim-test--dataset-1 http://www.w3.org/ns/prov#atLocation https://webcentral.uc.edu/eprof/media/attachment/eprofmediafile_4198.pdf https://w3id.org/delphi/resource/evidence/aristotle-pa02-42--claim-test--dataset-1 http://www.w3.org/ns/prov#wasDerivedFrom https://webcentral.uc.edu/eprof/media/attachment/eprofmediafile_4198.pdf https://w3id.org/delphi/resource/evidence/aristotle-pa02-42--claim-test--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:292077fb8fe6a42e39021aba6337b20a80b07fd16078067403e8185714a9cea8 https://w3id.org/np/RAPTX8hdhj34qScjZBkQPHRb8nPvqbLlvlbFn31wDqIk0/provenance https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://www.w3.org/ns/prov#SoftwareAgent https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 http://www.w3.org/2000/01/rdf-schema#label delphisci claim tester (grok-4.7;
