Abstract

fetched live from OpenAlex

Durante los dias 27 y 28 de Agosto de 1990 y en el marco del 13th Sedimentological Congress organizado por la International Association of Sedimentologists, tuvo lugar en la ciudad de Nottingham el Simposio Ichnofacies and ichnofabrics - sedimentological application of trace fossil research. Asimismo el Trace Fossil Research Group de la Society of Economic Paleontologists and Mineralogists (SEPM) organizo una reunion para comunicaciones de trabajos en desarrollo denominada 'Trace fossil research in progress. La organizacion del primer evento estuvo a cargo de John Pollard (U niversidad deManchester) y Tony Ekdale (Universidad de Utah), mientras que en el segundo caso la responsabilidad recayo sobre Chris Maples (Servicio Geologico de. Kansas). Considerando ambas reuniones se presentaron un total de 52 trabajos, participando activamente 44 icnologos de 17 paises (Alemania, Argentina, Brasil, Canada, China, Dinamarca, EE.UU., Francia, Holanda, India, Italia, Luxemburgo, Noruega, Nueva Zelanda, Polonia, Reino Unido y Sudafrica). Ricard Bromley (Universidad de Copenhagen) ofrecio una conferencia titulada Elite trace fossils, ichnotaphonomy and ichnoguilds que funciono a modo de presentacion de su reciente libro 'Trace Fossils. Biology and Taphonomy. En lo que respecta a la tematica de las reuniones, se cubrio una amplia gama de topicos. Se presentaron estudios de icnofaunas de distintos ambientes, tanto de casos actuales como de ambientes antiguos. Se marcaron nuevas tendencias que se van complementando con los enfoques clasicos. En particular, se expusieron gran cantidad de trabajos aplicados a la exploracion de hidrocarburos. Las lineas de investigacion relacionadas con este tema se basaron por lo general en el estudio de testigos corona y muy particularmente en el analisis de sus icnofabricas. Este campo promete ser uno de los mas fructiferos en icnologia tal cual lo demostraron presentaciones efectuadas sobre la Cuenca del Mar del Norte. Cabe mencionar dentro de las nuevas tendencias los estudios sobre tiering de comunidades endobentonicas y el creciente conocimiento sobre icnofaunas no-marinas que en los proximos anos podria modificar considerablemente a los conceptos clasicos. Al decir de los organizadores, la reunion efectuada en Nottingham fue la que conto con un mayor volumen de presentaciones de todas las realizadas hasta el presente en el campo de la icnologia. Este hecho parece reforzar la afirmacion de Ekdale, Bromley y Pemberton (SEPM Short Course 15, 1984) de que tras pasar por diversas etapas, la icnologia ha entrado por fin en su Edad de Oro.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
