Sericipterus – not a mandible: a tibia/fibula

% of readers think this story is Fact. Add your two cents.

Rarely this happens.
But when it does, it screws things up a bit.

I followed Andres et al. (2010) when they identified a long bone in Sericipterus as a mandible with surangular. Turns out no other sisters have such a gracile mandible devoid of tooth sockets.

Turns out the bone is a tibia + fibula, sometimes known as a crus.

Figure 1. Click to enlarge. From Andres et al. 2010, where they misidentify a tibia/fibula and call it a mandible with surangular.

Removing the mandible and adding a tibia/fibula makes better sense here, too.

Figure 2. Sericipterus with its crus (tibia/fibula) in place. It’s too gracile to be a mandible.

If you think Sericipterus looks like any other Dorygnathus, you’re right. Because it nests within Dorygnathus in the large pterosaur tree, wherever you put the tibia.
