Dinosaur of the day Titanosaurus, a dubious titanosaurian sauropod that lived in the Late Cretaceous.

In dinosaur news this week:

• Air sacs were invading sauropod bones in multiple ways in the Triassic—earlier than previously thought
• A new method to determine if scars on bones are from tendon attachments or air sac contact
• Ossified tendons aren't all completely ossified, some of them still have soft tissue in them
• Soft tissue plays a very important role in how animals breathe, smell, regulate their body temperature, communicate, and more
