As dinosaurs evolved to birds
Their teeth reduced and disappeared,
Though some kept jaw bones jagged sharp –
A modern goose is to be feared!
Teeth seem to be so useful
To hunting and to dine
That penguins have a toothed tongue,
Some modern chicks boast oral spines.
One hundred million years ago
Limusaurs did not concur.
They dropped their teeth in adult days,
A smooth beak they preferred.
And never seen before,
Fossils show that babies grew
And lost their teeth that tore.
More strange discoveries await
As fossils come to hand
To show us that surprising beasts
Once stalked across the land.
