Which one has become endangered due to extinction of Dodo (Raphus cucullatus)?
Sideroxylon grandiflorum is a long-lived tree in the family Sapotaceae, endemic to Mauritius. It is also known as tambalacoque or dodo tree. It is valued for its timber. Stanley Temple hypothesized that the dodo, which became extinct in the 17th century, ate tambalacoque fruits, and only by passing through the digestive tract of the dodo could the seeds germinate. Thus, due to the extinction of the dodo, the tree has become endangered. So, the correct answer is 'Sideroxylon grandiflorum'.
