Exceptionally preserved Cambrian trilobite digestive system revealed in 3D by synchrotron-radiation X-ray tomographic microscopy. [PDF]
PLoS ONE, 2012 The Cambrian 'Orsten' fauna comprises exceptionally preserved and phosphatised microscopic arthropods. The external morphology of these fossils is well known, but their internal soft-tissue anatomy has remained virtually unknown.

Arthroaspis n. gen., a common element of the Sirius Passet Lagerstätte (Cambrian, North Greenland), sheds light on trilobite ancestry. [PDF]
BMC Evol Biol, 2013 Background: Exceptionally preserved Palaeozoic faunas have yielded a plethora of trilobite-like arthropods, often referred to as lamellipedians. Among these, Artiopoda is supposed to contain taxa united by a distinctive appendage structure. This includes

A persistent influence of supernovae on biodiversity over the Phanerozoic. [PDF]
Ecol Evol, 2023 It shows the correlation between diversity and supernovae frequency. Abstract It is an open question what has constrained macroevolutionary changes in marine animal diversity on the time scale of the Phanerozoic. Here, we will show that supernovae appear to have significantly influenced the biodiversity of life.

Modularity in the trilobite head consistent with the hypothesized segmental origin of the eyes. [PDF]
Evol Dev, 2022 The degree and structure of modularity in the heads of two trilobite species, Calyptaulax annulata (left) and Cloacaspis senilis (right) are identified. Best fit hypotheses of modularity are consistent for both species: the eyes and anterior head highly covary (red), consistent with the anteriormost ocular segment of early arthropods.

Developmental traits and life strategy of redlichiid trilobites. [PDF]
Biol Rev Camb Philos Soc, 2023 ABSTRACT The developmental mode of four redlichiid trilobites is summarized, based upon exceptionally well‐preserved, articulated specimens from Cambrian Series 2 (stages 3 and 4) strata in southwestern China and South Australia. These relatively complete developmental sequences indicate a balanced rate in segment increase and addition to the thorax ...
