Palaeozoicum
Palaeozoicum[1] est aerathema stratigraphicum et aera geologica aeonis Phanerozoici infima. Palaeozoicum coepit abhinc annorum 541 000 ± 1 000 milium anni et abhinc annorum 251 902 ± 24 milium finem habuit. In sex periodos dividitur, quae ab infima ad supremam Cambrium, Ordovicium, Silurium, Devonium, Carboniferum, Permium appellantur.
Phanerozoicum, Palaeozoicum, Cambrium omnia incepta ex antiquissimis ichnofossilibus Treptichnus pedum dantur.
Nomen e verbis Graecis παλαιός 'antiquus' + ζῷον 'animal' ab Adamo Sedgwick anno 1838 Anglice sub forma Palæozoic series compositum est ut systemata Cambrium et Silurium comprehendat.[2][3]
