   Puijila darwini was a semi-aquatic carnivore which represents a morphological link in early pinniped evolution. Its fossil shows enlarged, probably webbed [3] feet, robust forelimbs and an unspecialized tail. This suggests that Puijila swam quadrupedally using its webbed fore and hind feet for propulsion. Phylogenetic studies including ...

   Apr 22, 2009 · Puijila is a massive boon for biologists trying to understand the evolution of pinnipeds, the group that includes seals, sea lions and walruses. It's not itself a direct ancestor, having branched off the evolutionary path that led to modern pinnipeds. It did, however, retain many of the same features that a direct ancestor would have had.

   Apr 23, 2009 · Puijila is a morphological intermediate in the land-to-sea transition of pinnipeds and provides new evidence concerning the evolution and biogeography of the earliest pinnipeds.

   Jan 16, 2020 · In the initial analysis (Rybczynski et al., 2009), Puijila was recovered in a clade with Enaliarctos, Potamotherium, and Amphicticeps, thereby supporting the notion Puijila is either a pinniped, a pinnipedimorph, or an earlier-diverging member of this clade. However, an extensive sampling of crown-group pinnipeds was not included.

   Was Puijila a pinniped?

   • Just as the earliest whales lived on land and had feet tipped with hooves, the earliest pinnipeds were likely land-dwelling animals that took millions of years to begin becoming adapted to life in the water. Rather than being a direct pinniped ancestor, then, Puijila likely represents the form of earlier pinniped forerunners.

   Was Puijila a transitional fossil?

   • "Puijila is a transitional fossil," Rybczynski explains. "It gives us a glimpse of what the earliest stages of pinniped evolution looked like, before pinnipeds had flippers. And it suggests that in the land-to-sea transition, pinnipeds went through a freshwater phase."

   Are pinniped Puijila phylogenetic?

   • In the present study, a series of phylogenetic analyses of morphological, molecular, and combined morphological-molecular datasets were conducted to investigate the relationships of 23 extant and 44 fossil caniforme genera, in order to test the phylogenetic position of putative stem pinniped Puijila within a comprehensive evolutionary framework.

   Are seals and sea lions descendants of Puijila?

   • Today’s seals and sea lions are not direct descendants of Puijila, but the otter-like mammal represents what pinniped ancestors were like at one point in the distant past. Paleontologists know this because rock layers of about the same age—about 24 million years old—as Puijila contain the remains of the early pinniped Enaliarctos.
