- F. Scott Fitzgerald (Wikipedia)
Francis Scott Key Fitzgerald (September 24, 1896 – December 21, 1940) was an American novelist, essayist, and short story writer. He is best known for his novels depicting the flamboyance and excess of the Jazz Age—a term he popularized in his short story collection Tales of the Jazz Age. During his lifetime, he published four novels, four story collections, and 164 short stories. Although he achieved temporary popular success and fortune in the 1920s, Fitzgerald received critical acclaim only after his death and is now widely regarded as one of the greatest American writers of the 20th century.
- Dimetrodon (Wikipedia)
Dimetrodon (/daɪˈmiːtrəˌdɒn/ or /daɪˈmɛtrəˌdɒn/; lit. ’two measures of teeth’) is an extinct genus of non-mammalian synapsid belonging to the family Sphenacodontidae that lived during the Cisuralian age of the Early [Permian](Permian period, around 295–272 million years ago. With most species measuring 1.7–4.6 m (5.6–15.1 ft) long and weighing 28–250 kg (62–551 lb), the most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It was an obligate quadruped (it could only walk on four legs) and had a tall, curved skull with large teeth of different sizes set along the jaws.
