Spinosaurids had powerful enough jaws and teeth to go after large prey, just not sharp enough to take out bites. Plus, more on the aquatic spinosaurs debate, and more spinosaur updates.

Dinosaur of the day Tachiraptor, a small carnivorous theropod that was found in the mountains of Venezuela.

In dinosaur news this week:

• Spinosaurids had the skull and teeth to go after large prey
• Instead of crocodile mimics, maybe spinosaurs should be considered phytosaur mimics
• Spinosaurus had at least one other spinosaurine living along side it in the Kem Kem beds in Morocco
• A tooth in Thailand that was long thought to be from an ichthyosaur was actually from a spinosaur

• Scientists caution on how to estimate sizes and body shapes of extinct animals (be careful what animals you compare it to)

Dinosaur of the day Saichania, an ankylosaur known for its pretty face.

In dinosaur news this week:

• There’s a new ceratopsian dinosaur, Sasayamagnomus saegusai
• There’s a new titanosaur sauropod, Qunkasaura pintiquiniestra
• Damage to a number of tails may mean the sauropodomorph Plateosaurus often had to live with its injuries
• Long necked dinosaurs did care! The basal sauropodomorph Lufengosaurus probably took care of and fed its young
