New Theories On Dinosaur Behaviour
The late 1960s also saw several new theories on the way dinosaurs behaved, often involving sophisticated social behaviour.
On the basis of trackways, Bakker argued that sauropod dinosaurs moved in structured herds, with the adults surrounding the juveniles in a protective ring. However, shortly afterwards this particular interpretation was challenged by Ostrom among others, although the venerable dinosaur track expert Roland T. Bird apparently agreed with Bakker.
The first rigorous study of dinosaur nesting behaviour came in the late 1970s, when palaeontologist Jack Horner showed that the duckbilled dinosaur Maiasaura cared for its young.

Famous quotes containing the words theories and/or behaviour:
“It takes twenty or so years before a mother can know with any certainty how effective her theories have been—and even then there are surprises. The daily newspapers raise the most frightening questions of all for a mother of sons: Could my once sweet babes ever become violent men? Are my sons really who I think they are?”
—Mary Kay Blakely (20th century)
“I cannot be much pleased without an appearance of truth; at least of possibility—I wish the history to be natural though the sentiments are refined; and the characters to be probable, though their behaviour is excelling.”
—Frances Burney (1752–1840)
