#FossilAdventCalendar Day 5
#MarineLifeMonday
Most #fish species alive today, from #salmon to #guppies, belong to a single group. In the #Devonian, though, many lineages were abundant. #Quebec's 🇨🇦 #ParcNationalDeMiguasha provides a glimpse of this #biodiversity, which includes #lungfish such as Scaumenacia curta, shown here in the #RoyalOntarioMuseum. Their lobed fins contain many of the same #bones as our arms, evidence that lungfish are much more closely related to us than to most other fish.
