Galesauridae is a family of Therapsid reptiles. Along with the family Thrinaxodontidae and the large clade Eucynodontia (which includes the mammals), it makes up the unranked taxon called Epicynodontia. Galesaurids first appeared in the very latest Permian period, just a million years (or perhaps only a thousand years) before the greatest extinction of all time, the Permian-Triassic extinction event.

  • Galesauridae is a family of Therapsid reptiles. Along with the family Thrinaxodontidae and the large clade Eucynodontia (which includes the mammals), it makes up the unranked taxon called Epicynodontia. Galesaurids first appeared in the very latest Permian period, just a million years (or perhaps only a thousand years) before the greatest extinction of all time, the Permian-Triassic extinction event. Galesaurids are the most primitive of the epicynodonts. They may have resembled the basal cynodonts, such as the procynosuchids and may have descended from a procynosuchid-like ancestor, but the galesaurids were more advanced than the basal cynodonts. It is clear that, like many other epicynodonts, many galesaurids had a complete secondary palate, which allowed them to swallow food while breathing, and the dentary bone was enlarged relative to those of their ancestors. Their temporal fenestrae are much larger than those of the procynosuchids, but not as large as in more advanced epicynodonts. Their snouts are broad, rather than tall, and they may have walked erect, with the legs beneath the body like most other cynodonts. Galesaurid fossils are found almost worldwide. They were among the survivors of the Permian-Triassic extinction event, but they became extinct in the Middle Triassic epoch, as did the therocephalians. Genera of the family Galesauridae include the namesake Galesaurus.
  • I Galesauridae, insieme alla famiglia Thrinaxodontidae e al largo clade Eucynodontia (che comprende i mammiferi) comprendono il taxon chiamato Epicynodontia. I Galesauridi apparvero per la prima volta nel tardo Permiano, appena un milione di anni (o forse solo un migliaio di anni) prima dell'Estinzione di massa del Permiano-Triassico. I Galesauridi sono i più primitivi fra gli Epicynodontia. Potrebbero aver somigliato ai cinodonti di base, come i procinosuchidi e potrebbero essere stati i discendenti di un antenato simile procinosuchide, ma i galesauridi erano più avanzati dei cinodonti di base. È chiaro che, come molti altri epicinodonti, molti galesauridi avevano un palato secondario completo, che permetteva loro di inghiottire il cibo mentre respiravano, e le ossa dentarie si erano ingrossate rispetto a quelle dei loro antenati. Le loro ossa temporali sono molto più grandi di quelle dei procinosuchidi, ma non come quelle di epicinodonti più avanzati. I loro musi sono larghi, piuttosto che alti, ed essi avrebbero potuto camminare eretti, con le zampe sotto il corpo come nella maggior parte degli altri cinodonti. I fossili di Galesauride sono stati trovati in quasi tutto il mondo. Furono tra i sopravvissuti della Estinzione di massa del Permiano-Triassico, ma si estinsero nel Triassico medio, insieme ai therocephalia. Uno dei generi più notevoli della famiglia dei Galesauridi è Galesaurus.

Aan het einde van het Vroeg-Trias stierven de galesauriërs uit en werden vervangen door de chiniquodonten en Cynognathus. Ondanks het feit dat de galesauriërs nog vrij primitief waren, hadden deze dieren wel al verschillende zoogdierachtige kenmerken zoals een gevarieerd gebit en een secundair gehemelte, dat de galesauriërs is staat stelde om tegelijkertijd te eten en te ademen. Waarschijnlijk waren de galesauriërs ook warmbloedig.
