As per both classical and contemporary ulema, the ayah (27:82) in the question refers to the Dabbatul Ardh (دابة الأرض ) also known as the beast of the Earth. It is among one of the ten major signs of the Hour.
It is narrated on the authority of Abu Huraira that the Messenger of
Allah (ﷺ) observed:
When three things appear faith will not benefit one who has not
previously believed or has derived no good from his faith: the rising
of the sun in its place of setting, the Dajjal, and the beast of the
Sahih Muslim, Book 1, Hadith 305
According to a hadith from Tirmidhi, the beast will have the Seal of Solomon and the Staff of Moses. It will mark the believers and the kaafirs. As for the believer, it will make his face shine brightly, as a sign of his faith, and as for the kaafir, it will mark his nose with a sign of his disbelief.
Narrated Abu Hurairah: that the Messenger of Allah (ﷺ) said: "A beast
will emerge from the earth. With it shall be the ring of Sulaiman and
the staff of Musa. It will brighten the face of the believer, and
stamp the nose of the disbeliever with the ring, such that when the
people gather to eat, it will be said to this one: 'O believer! and to
that one: 'O disbeliever!'"
Grade : Da'if
As the ayah in the question states, the Beast will speak to people. The rising of the sun from the west and the emergence of this beast have a very short interval between them. After this no person will benefit from their good deeds if they had not already believed as they (or their recent ancestors) would have already gone through the period of the Mahdi (who some scholars regard as the bridge between the minor signs and the 10 major signs), Dajjal,the 3 earthquakes, Jesus/Isa (AS), tribes of Gog/Yajuj and Magog/Majuj but still some of them again disobeyed Allah's command.
Eventually as Allah wills the remaining signs will take place.
One of the Hadiths states that the major signs will follow each other in succession like beads of a necklace when the string is cut and so they (the beads) fall in succession.
