Alfred Romer was born in White Plains, New York, the son of Harry Houston Romer and his wife, Evalyn Sherwood. He was educated at White Plains High School.BOOK, Biographical Index of Former Fellows of the Royal Society of Edinburgh 1783–2002, July 2006, The Royal Society of Edinburgh, 0 902 198 84 X,weblink He studied at Amherst College achieving a Bachelor of Science Honours degree in biology and Columbia University pursuing with a M.Sc in Biology and graduating with a doctorate in zoology in 1921. Romer joined the department of geology and paleontology at the University of Chicago as an associate professor in 1923. He was an active researcher and teacher. His collecting program added important Paleozoic specimens to the Walker Museum of Paleontology. In 1934 he was appointed professor of biology at Harvard University. In 1946, he also became director of the Harvard Museum of Comparative Zoology (MCZ). In 1954 Romer was awarded the Mary Clark Thompson Medal from the National Academy of Sciences.WEB, Mary Clark Thompson Medal,weblink National Academy of Sciences, 15 February 2011, yes,weblink" title="">weblink December 29, 2010, He was awarded the Academy's Daniel Giraud Elliot Medal in 1956.WEB, Daniel Giraud Elliot Medal,weblink National Academy of Sciences, 15 February 2011, yes,weblink" title="">weblink August 1, 2012,

Evolutionary research

Romer was very keen in investigating vertebrate evolution. Comparing facts from paleontology, comparative anatomy, and embryology, he taught the basic structural and functional changes that happened during the evolution of fishes to primitive terrestrial vertebrates and from these to all other tetrapods. He always emphasized the evolutionary significance of the relationship between the form and function of animals and the environment.Through his textbook Vertebrate Paleontology Romer laid the foundation for the traditional classification of vertebrates. He drew together the (then) widely scattered taxonomy of the different vertebrate groups and combined them in a simplified scheme, emphasizing orderliness and overview. Based on his research of early amphibians, he reorganised the labyrinthodontians."Romer, Alfred Sherwood." Complete Dictionary of Scientific Biography. 2008. Retrieved May 25, 2011 from Romer's classification was followed by many subsequent authors, notably Robert L. Carroll, and is still in use.

Kronosaurus queenslandicus skeleton

(File:Kronosaurus queenslandicus.jpg|thumb|left|K. queenslandicus at Harvard University which may have been reconstructed with too many vertebrae)Prior to Romer's tenure as MCZ director, the Museum sent an expedition to Australia in 1931–1932 to gather specimens and study live animals. Yet then-graduate student William E. Schevill, the team's fossil enthusiast, remained in Australia beyond the venture and, in the winter of 1932, was told by the rancher R.W.H. Thomas of rocks with something "odd" poking out of them on his property near Hughenden.Mather, Patricia, with Agnew, N.H. et al.

The skull—which matched the holotype jaw fragment of K. queenslandicus—was prepared right away, but time and budget constraints put off restoration of the nearly complete skeleton - most of the bones of which remained unexcavated within the limestone blocks - for 20 years. This interim ended when they came to the attention of Godfrey Lowell Cabot - Boston industrialist, philanthropist, and founder of the Cabot Corporation - "who was then in his nineties had been interested in sea serpents since childhood." (File:Kronosaurus scale.svg|thumb|right|K. queenslandicus scale diagram, showing the size of the restored Harvard skeleton along with a more accurate estimate)Having formerly question Dr. Romer about the existence and reports of sea serpents and it thus occurred to Romer to tell Mr. Cabot about the skeleton in the museum closet. Godfrey Cabot thus asked how much a restoration would cost and "Romer, pulling a figure out of the musty air, replied, 'Oh, about $10,000.'" Romer may not have been serious but the philanthropist clearly was because the check for said sum came shortly thereafter.The Rarest of the Rare: Stories Behind the Treasures at the Harvard Museum of Natural History (Hardcover) – October 26, 2004 Two years - and more than $10,000 - later, following the careful labor of the museum preparators, the restored and mounted skeleton was displayed at Harvard in 1959. However, Dr. Romer and MCZ preparator Arnold Lewis confirmed that same year in the institution's journal Breviora that "erosion had destroyed a fair fraction of this once complete and articulated that approximately a third of the specimen as exhibited is plaster restoration."Romer, A. S. and A. D. Lewis. 1959. A mounted skeleton of the giant plesiosaur Kronosaurus. Breviora 112:1-15. Furthermore, the original (real) bones are also layered in plaster; a fact that, while keeping the fossils safe, makes it difficult for paleontologists to study it - an issue which factors into the controversial question of the true size of the Kronosaurus queenslandicus.

Size issues

Body-length estimates, largely based on the 1959 Harvard reconstruction, had previously put the total length of Kronosaurus at {{convert|12.8|m|ft}}.Romer AS, Lewis AD. 1959. A mounted skeleton of the giant plesiosaur Kronosaurus. Breviora 112: 1-15. However, more recent studies, comparing fossil specimens of Kronosaurus to other pliosaurs suggests that the Harvard reconstruction may have included too many vertebrae, exaggerating the previous estimate, with the true length probably only {{convert|9|to|10.5|m|ft}}.Kear BP. 2003.

A genus of early captorhinids is named Romeria after Romer, as is Romeriida (the name for a clade that contains the diapsids and their closest relatives). In July 2007 a species of non-dinosaurian dinosauromorph was named Dromomeron romeri, "the first part meaning 'running femur,' the latter in honor of paleontologist Alfred Sherwood Romer, a key figure in evolution research". The finding of these fossils was hailed as a breakthrough proving dinosaurs and other dinosauromorphs "lived together for as long as 15 million to 20 million years."NEWS, Grad student finds 'pre-dinosaur', 2007-07-20, Andrew Herrmann,weblink Chicago Sun-Times, yes,weblink" title="">weblink 2008-10-13, JOURNAL, Irmis, R.

It was initially described as the oldest known amniote,JOURNAL, Baird, D., Carroll, R.L., vanc, 1967, Romeriscus, the oldest known reptile, 1721645, Science, 157, 3784, 56–59, 10.1126/science.157.3784.56, but this is because limnoscelids were, at that time, considered amniotes by some authors. A subsequent study showed that the fossil lacks diagnostic characters and can only be assigned to Tetrapoda.JOURNAL, Reisz, R.R., Laurin, M., vanc, 1992, A reassessment of the Pennsylvanian tetrapod Romeriscus, Journal of Vertebrate Paleontology, 12, 4, 524–527, 10.1080/02724634.1992.10011478, Romer was the first to recognise the gap in the fossil record between the tetrapods of the Devonian and the later Carboniferous period, a gap that has borne the name Romer's gap since 1995.JOURNAL, Ward, P., Labandeira, C., Laurin, M., Berner, R.
