Recommendation: “The very first occurrence of an avian-style respiratory infection in a non-avian dinosaur” by D. Cary Woodruff, Ewan D. S. Wolff, Mathew J. Wedel, Sophie Dennison and Lawrence M. Witmer, 10 February 2022, Scientific Reports.DOI: 10.1038/ s41598-022-05761-3.

Cary Woodruff and associates took a look at 3 of the bones from MOR 7029s neck and identified bony protrusions that had a unusual and irregular shape and texture. Based on the area of the abnormal bony protrusions, the scientists recommend that they formed in action to an infection in MOR 7029s air sacs, which then spread into its neck bones. As aspergillosis can be deadly in birds if unattended, MOR 7029 might have eventually passed away as a result of this infection, they add.

Note that the lung illness contaminating this animal would not have been externally evident, but the probable pneumonia-like outside symptoms would have included coughing, labored breathing, nasal discharge, fever, and weight reduction, among others.

The fossilized remains of a young diplodocid– a big, long-necked herbivorous sauropod– may supply the very first proof of a respiratory infection in a dinosaur, according to a research study released in Scientific Reports. The findings increase our understanding of the diseases that affected dinosaurs.

Cary Woodruff and colleagues took a look at 3 of the bones from MOR 7029s neck and determined bony protrusions that had an irregular and unusual shape and texture. These air sacs would have connected to MOR 7029s lungs and formed part of the dinosaurs respiratory system.

Based on the area of the irregular bony protrusions, the researchers recommend that they formed in action to an infection in MOR 7029s air sacs, which then spread out into its neck bones. The authors speculate that this could have been brought on by a fungal infection comparable to aspergillosis, a typical respiratory illness that impacts reptiles and birds and can result in bone infections. They recommend that if MOR 7029 had actually been contaminated with aspergillosis, it might have experienced influenza or pneumonia-like symptoms such as weight loss, coughing, fever, and breathing troubles. As aspergillosis can be fatal in birds if without treatment, MOR 7029 might have eventually passed away as a result of this infection, they add.
