description Lotagnostus Overview
Lotagnostus is a genus of small agnostid trilobites from the Cambrian Period. Agnostids were generally diminutive and had reduced or absent eyes, and Lotagnostus is commonly treated as a blind form. Its broad geographic distribution gives it value in biostratigraphy, the use of fossils to correlate rock layers, because occurrences of the genus can help compare Cambrian strata across different paleocontinents.
help Lotagnostus FAQ
What kind of trilobite was Lotagnostus?
Lotagnostus was a small agnostid trilobite from the Cambrian Period. Agnostids were generally tiny compared with many other trilobites.
Was Lotagnostus blind?
Lotagnostus is commonly treated as a blind form, reflecting the reduced or absent eyes typical of many agnostid trilobites.
Why is Lotagnostus useful in biostratigraphy?
Its broad geographic distribution and fossil occurrence can help compare Cambrian rock layers. Biostratigraphy uses fossils to identify and correlate the relative ages of strata.
What does Lotagnostus look like?
It had the compact body form associated with agnostid trilobites, including a cephalon and pygidium of similar general size. Its small size and reduced eyes distinguish it from many larger, more visibly eyed trilobites.
