This sparrow-sized flier, which belonged to the enantiornithine group of toothed birds, lived between 121 and 125 million years ago, consuming a diet of smaller hard-shelled creatures such as insects or crabs.
As rare as hen's teeth might be today, it seems that the group to which this bird belonged to were evolving new and toothy ways to exploit a variety of ecological niches - at a time when other birds were losing their dentitions.
Although small, this bird and it's relatives were certainly toothsome. I like to think of them as Darwin finches with attitude...
