This is the Irish Elk (Megaloceros giganteus) is an species that is known for its gigantic antlers and its incredibly strong positive allometry. Contrary to popular thinking, the sheer size of its antlers --- was maladaptive; sure but the most of the extinction pressures came from outside of its environment, however, the species became an textbook example of sexual selection due to its lack of ability to respond to its pressures(Stephen 1974), the antlers inhibiting its ability to survive in its environment. (Worman & Kimbrell, 2008), The Irish Elk went extinct around ~7,700 years and had survived multiple glacial-intergacial cycles, however, what was the resurgence of humans and the resurgence of an human habitat, and later Antler size decreased; due to the new hostile environment that surrounded it and due to the lower reproductive yield of its female population, In truth, if nearly all of the male gender of the species was wiped out then it would still survive (Worman & Kimbrell, 2008).
(The Irish Elk is listed as M, As you can clearly see. The Irish Elk is nearly on the LSE Regression line)
Additionally, the initial qualitative work was shoddy at best:

Such inaccuracy in comparative data appears common, and there is little reason to expect comparative data for ungulates to be much better than the scandalously error-ridden data on body size that has fueled an industry of comparative research on primates (Sandel et al., 2016; Smith & Jungers, 1997).
The deer data are further void of any indication of uncertainty or sample sizes. Later compilations of antler data, such as by Plard et al. (2011), may be of better quality, but are still lacking measures of uncertainty and documentation of origin.
(DNR - Irish Elk would still have survived under sexual selection, sexual selection was maladaptive for the species but the real problem came with reduced reproductive yield of its females, females still screwed up the species and females alone led to its extinction)The observed average of the Irish elk is thus only 1% above the prediction, and this analysis supports Gould's hypothesis that the “gigantic” antlers of the Irish elk are as expected for a deer of its size
