Did the death erection of some extinct animals, such as Mammoths, suggest they were killed by local and instant catastrophic mass mortality events, that also sometimes triggered autoerotic asphyxiation?
In 1986 at Lake Nyos over 3000 cattle and 1500 people were killed by a limnic eruption of their Volcano, as suffocating gases flowed through their village.
In 1935 Innokenty Tolmachoff stated the erected male genital of the Beresovka Mammoth proved the animal suffocated in mud because this indelicate detail was inexplicable in any other way.

On Thursday, April 6, 2006, four experienced Mammoth Mountain Ski Patrollers were inspecting the mountain after a series of heavy snowstorms. The patrollers were fencing off the fumarole, on Christmas Bowl run when the snow around the vent collapsed.
In this instance, the tremendous snowfall had temporarily blocked the vent and a build-up of gas occurred beneath the snowpack creating unstable conditions. Two patrollers fell into the approximately 6-ft hole, down 21 feet of snow to the earth. Two patrollers attempting to help descended into the hole.
The two that fell and one who attempted to rescue them passed due to asphyxiation by the volcanic gasses.

In his article about the Indelicate Details of Alaskan Muck, that is pure Tim Cullen at his best, he explores the Sexual Habits of the Adelie Penguin's, autoerotic asphyxiation, Mammoths including the Beresovka Mammoth, postmortem Priapism, limnic eruptions (Lake Nyos CO2 example), close encounters with comets, gas asphyxiation and gas poisoning (Carbon dioxide, Hydrogen sulfide, Cyanide, Methane), Livor Mortis, and much much more.
It’s difficult to draw valid conclusions when indelicate details are omitted. This is true in the modern era. This is especially true with historical sources. In 1908 Richard Lull “supposed” the Beresovka Mammoth fractured a hip and foreleg when it slipped into “a crevasse” before bursting a blood vessel as it frantically fought to escape.
Wikipedia echoes the suggestion that the Beresovka Mammoth “may have died of asphyxiation” because of this indelicate detail i.e. “its erect penis”. To get a handle on the connection between “asphyxiation” and an “erect penis” it’s necessary to revisit autoerotic asphyxiation.

It is tentatively hypothesized that both Changmiania liaoningensis specimens were suddenly entrapped in a collapsed underground burrow while they were resting, which would explain their perfect lifelike postures and the complete absence of weathering and scavenging traces.
Such a perfect preservation of the skeleton in a lifelike posture, as observed in both the holotype and referred specimen of Changmiania liaoningensis and also in countless fossils from the Lujiatun Beds, implies that the animals were rapidly entombed while they were still alive.
It has also been proposed that some of the most fossiliferous locations in the Yixian Formation, and particularly in the Lujiatun Beds, are the result of instant catastrophic mass mortality events preserved in tuffaceous ashes; in such a Pompeii-like scenario, the main cause of death for the vertebrates from the Lujiatun beds would have been asphyxiation by toxic volcanic gases of ashes.

Lake Nyos origin of mass Asphyxia deaths
Lake Nyos, located in Cameroon, West Africa, had no signs of volcanic activity or that natural disaster could take place. It was a quiet, blue coloured, beautiful lake, surrounded by small villages where the livelihood of the villagers was based on farming and raising cattle. On the night of the 26th of August, 1986, however, everything changed.
According to the reports of the few who managed to survive, it was in the evening when the villagers heard a rumbling sound. Leaving their homes to check on the source of the noise, they saw a tall fountain of water spouting out of Lake Nyos. Accompanying this fountain was the release of a white cloud of gas, that, as it grew bigger and taller, up to 100 m in height, settled on the surface of the lake and started to flow down the valley, forming a river of white gas 50 m tall. This river of gas flowed through the villages and the people in the villages started to lose consciousness, collapsing to the ground. The livestock such as cattle also lost consciousness.
Because carbon dioxide is denser than air, the flow hugged the ground, forming a 50 m high flow. Furthermore, any living thing (that breathes oxygen) that inhaled the surrounding air that was more than 15% concentrated in carbon dioxide died on the spot. If it was less than 15% concentrated in carbon dioxide, both animal and people would pass out, but eventually after time would regain consciousness.
After the flow of carbon dioxide had dissipated, 1700 villagers and over 3000 various livestock had died. In the village that was first hit by the carbon dioxide flow, only 4 people survived because they had run up to higher ground. Before the ‘eruption’, Lake Nyos was beautiful and blue. After the ‘eruption’ with the lake water being saturated with carbon dioxide, Lake Nyos was a murky brown colour.

Eternal sleeper dinosaur or put to sleep forever?
Both Changmiania liaoningensis were in nearly pristine condition. The name means "eternal sleeper" in Chinese, because both of the dinosaurs appeared to have been buried while alive with their eyes closed, looking as though they were asleep.
The researchers suggest the reason for the quick demise and nearly pristine condition was likely due to a volcanic eruption catching them both as they slumbered in their burrow. The area where the dinosaurs were discovered was part of the plain that had been covered in debris from an ancient massive volcanic eruption, which had also covered many other creatures. The area is a well-known archeological dig site.
The researchers suggest that the burrows in which the dinosaurs had been sleeping likely collapsed under the weight of the debris from the volcano, giving the dinosaurs no chance to dig themselves out.
They note also that the tails of the dinosaurs had been stretched out due to stiffness.
