    The median eyes of trilobites by Brigitte Schoenemann, Euan N. K. Clarkson

    Published 2023-03-01
    “…Abstract Arthropods typically possess two types of eyes—compound eyes, and the ocellar, so called 'median eyes'. Only trilobites, an important group of arthropods during the Palaeozoic, seem not to possess median eyes. …”

    Modelling enrolment in Cambrian trilobites by Esteve, J, Rubio, P, Zamora, S, Rahman, I

    Published 2017
    “…Trilobites were capable of enrolling in different ways based on the flexible articulation of thoracic segments and associated interlocking devices; the type of enrolment (spiral or sphaeroidal) is thought to have largely depended on the coaptative devices that each trilobite used to enclose the body. …”

    Phylogenetic and biogeographic analysis of sphaerexochine trilobites. by Curtis R Congreve, Bruce S Lieberman

    Published 2011-01-01
    “…BACKGROUND: Sphaerexochinae is a speciose and widely distributed group of cheirurid trilobites. Their temporal range extends from the earliest Ordovician through the Silurian, and they survived the end Ordovician mass extinction event (the second largest mass extinction in Earth history). …”

    Vibronic interactions in trilobite and butterfly Rydberg molecules by Frederic Hummel, Peter Schmelcher, Matthew T. Eiles

    Published 2023-02-01
    “…Ultralong-range Rydberg molecules provide an exciting testbed for molecular physics at exaggerated scales. In the so-called trilobite and butterfly Rydberg molecules, the Born-Oppenheimer approximation can fail due to strong nonadiabatic couplings arising from the combination of radial oscillations and rapid energy variations in the adiabatic potential energy curves. …”

    Abnormal xiphosurids, with possible application to Cambrian trilobites by Bicknell, R, Pates, S, Botton, M

    Published 2018
    “…We compare injuries on extant xiphosurids to extinct Cambrian trilobite injuries to suggest that rare cephalic injuries to trilobites were incurred during soft-shelled exoskeletal stages. …”
