Read "Teeny skull trapped in amber belongs to smallest dinosaur ever found", By Ben Guarino.
Select the sentence from the article that suggests paleontologists were able to make guesses about the dinosaur only after a close examination.
(A) "If it's indeed a dinosaur, it's definitely the smallest known extinct dinosaur," said Ohio University paleontologist Lawrence Witmer.
(B) The researchers' analysis placed the animal "fairly deep in the origin of birds," Schmitz said, but with a "lot of uncertainty."
(C) In the past, when describing fossils, paleontologists have mistaken young animals for unusually small species.
(D) The dinosaur probably ate insects and other invertebrates, Schmitz said.
Answer: (B) The researchers' analysis placed the animal "fairly deep in the origin of birds," Schmitz said, but with a "lot of uncertainty."
Explanation:
The author of the study, a paleobiologist at the Keck Science Center, was Lars Schmitz. Schmitz first approach through a digital scan of the creature's skull led to the belief that it was an animal in the origin of birds, but this idea carried a "lot of uncertainty."
It was only after closer examination they could conclude that Oculudentavis khaungraae was likely the smallest species of a dinosaur ever found.
