Answer

No. According to modern scientific understanding, dinosaurs became extinct millions of years before human beings appeared.

In Jain tradition, Bhagwan Rishabhdev, the first Tirthankar of the present avasarpini kaal, lived in an extremely ancient period of human civilization, but he is still understood within the cycle of human beings and spiritual development—not in the age of dinosaurs.

Explanation

Bhagwan Rishabhdev is described in Jain tradition as the first Tirthankar of this time cycle. He taught humanity important aspects of civilized life, such as agriculture, arts, social organization, and spiritual discipline.

Dinosaurs, however, belong to a much earlier prehistoric period according to modern science. Jain scriptures focus on spiritual truth, karma, liberation, conduct, and cosmic time cycles; they do not describe Bhagwan Rishabhdev living among dinosaurs.

Spiritual Understanding

The importance of Bhagwan Rishabhdev is not connected to dinosaurs or prehistoric animals. His significance is that he re-established the path of Dharma and showed the way toward self-control, non-violence, renunciation, and moksha.

Takeaway

So, in simple terms: dinosaurs were not around when Bhagwan Rishabhdev was present. Bhagwan Rishabhdev belongs to Jain sacred history of humanity, while dinosaurs belong to a much earlier natural history.
