Luancaia igen. nov., a molting trace fossil

Research in Northern Spain yielded some spectacular Devonian trace fossils. While they may look superficially similar to classic resting traces like Rusophycus, they lack any scratch imprint and have a distinctive axial ridge. In fact, their morphology is strikingly similar to the dorsal side of the euarthropod Camptophyllia. Detailed research by Mangano and workers in Scientific Reports determined that these traces instead represent evidence of infaunal molting. Their new article formally describing these traces and the palaeoecologic and paleonenvironmental implications they hold is available for free until January 16th through this link: https://authors.elsevier.com/c/1c8ca73N~0BeE

Congratulations to Gustavo!

This past Monday our very own Gustavo Valencia successfully defended his Master’s thesis. A big congratulations to Gustavo on this great accomplishment! His thesis examined both the ichnology and fluvial architecture of the Miocene Vinchina Formation in the Vinchina Basin from NW Argentina. Keep an eye out for a journal article on the subject soon! You can hear about the research from Gustavo himself in his final seminar to the University of Saskatchewan here.

Congratulations on a successful defence!

Mariano, a few minutes after earning the title of Dr. Arregui!

On September 2nd another member of our ichnofamily, Mariano Arregui, successfully defended his thesis! His thesis studied transitional marine environments from the Lajas Formation (Middle Jurassic, Neuquén Basin, West Argentina). You can read more about his work on his ResearchGate page, where he delves into topics like the relationship between phytodetrital pulses and shrimp burrow linings or the palaeoenvironmental interpretation of the formation in the subsurface. A massive congratulations to Dr. Arregui on this incredible accomplishment!
