Sloppy CNN: Scientists find new clue in what led to megalodon’s demise

Sloppy CNN: Scientists find new clue in what led to megalodon’s demise. Quoting,
Through an analysis of fossilized megalodon teeth, scientists have discovered the extinct shark was partially warm-blooded, with a body temperature around 7 degrees Celsius (44 degrees Fahrenheit) warmer than estimated seawater temperatures at the time, according to a study published last week in the journal Proceedings of the National Academy of Sciences.
This is wrong; 44 should be 12.6. It seems someone mistakenly  used the formula for Celsius to Fahrenheit temperature conversion:
Temp_F  = Temp_C *9÷5 + 32
To be converted is the relationship of the Celsius unit of measure to the Fahrenheit unit of measure, which is:
Fahrenheit degrees  per Celsius degree = 9÷5
The number 32 must not be added.
This is sloppy journalism.
